Title: C14 aftermarket LED brake light / ???
Post by: stevewfl on June 10, 2012, 06:56:10 PM
I bought an aftermarket 4-LED light I use as a second brake light.  I built a custom mount and its under my license plate running along the bottom of it. I'm worried its TOOOOOOO BRIGHT.  Its a light made for police cars and ambulances.  I'm running it "alternating pattern" and this concerns me more as its an attention getter. At night it lights up houses down the street.

My question to those who have such a product:

Do you have it in steady brake light mode or "alternating"?  If in alternating, are you concerned it will really p*ss people off behind you at night, and are you concerned some lunatic with a carry permit will shot you over it?

Is there a "night mode" for these lights to avoid blinding people at night or scaring grandma into heart attack?

How directional are the LED's? Could you aim them down a little to lessen the glare to other drivers? I know the Hyperlites have a definite angle to them that could be "aimed" in some fashion.

Yeah I looked at that but from any angle they are BRIGHT, like they're designed to be seen from any angle.

I went out tonight and rode and wow, I can see them flashing against the lens of people stopped behind me wearing glasses

Neither.  I have an Admore and it has a built-in timer.  It will flash rapidly 4 times, then go solid.  And it won't flash again until it has been 20-30 seconds without using the brake, to prevent annoyance during stop and go traffic.

I would be concerned about that, yes.  By the way, several companies sell a module that will do the rapid flash and then solid and delay before reflash, so it can be added to any light, even the stock one.

There is a difference between good visibility and just annoying people.  It is just like the people who run with their highbeams on in the day- who don't care how annoying it is to other drivers, because all they care about is being "seen", when in reality, it can be more than just annoying- it can dazzle and blind some people, and make it HARDER to see where the bike is.  But there is a solution for that too- properly adjusted running lights...

This one has 18 options, just wondering which people use.  Its so bright its about dangerous.

my track bikes get so many mods it'd take a page or two for a listing. this bike is just a beater road trip bike, its luck to get a washing off heh

it has a givi E55 and TM, GPS, etc but I wanted this brake light before I hit NYC and such on my way up to maine for lobster and canada just to raise %$#$.  some of us ride a little ways =)

You might consider:

Lens tinting spray.  I am no fan of blacked out taillights, but this might be a reasonable application.
Vinyl windshield tinting film might be another option.  Since the amount needed for the application would be so small, a tint shop might just give you the film from their leftover scraps.
Edit:  For all I know, there may be film made specifically for taillights as well.

FWIW, I appreciate your consideration of your fellow riders and drivers in this matter.

Steve, I was having a conversation with someone I work with today about LED lighting (I work in the electrical supply industry).  He was telling me that some LED's can be dimmed with conventional dimmers.  If I get time, I may go buy a super bright LED (might even have one already) and go down to Radio Shack and pick up a cheap DC dimmer and try it.  Just food for thought right now.  If it works, you would have a completely variable brightness control.

I have a Whelen Engineering model, it's bright as heck also. But I mounted it way low where the reflector was located. Right now, it's hooked to a standard relay so it's on all the time. I used to have a DEI pulse timer relay, cannot find it anywhere. So I found a cheap one on Ebay and just ordered it. I want to have the light flashing for only a set length of time, so it won't be so terribly bright on anyone stopped up close to the bike. At night just the reflection of the light bouncing off is almost overwhelming.

In regards to your question about "night mode," that would depend on the unit. Many lightbars and lights do have a circuit to toggle from high to low and back again. But I don't know about your unit and my Whelen will not either. It has three wires, two for power and one for programming. I installed a momentary switch under the seat to program if I like on the fly. I have mine set for a series of fast flashes and then slower, longer pulses.

That is not likely to work.  LED's can be dimmed a little bit by lowering the voltage, but they are often not happy about it.  The typical way LED's are "dimmed" is to strobe them at very high frequencies.  I think you would have better results by popping off the lens and obscuring it a bit with something.  Maybe something as simple as a piece of paper...  (been there, done that :)  )
Title: Re: C14 aftermarket LED brake light / ???
Post by: Breaker19 on June 13, 2012, 06:03:53 PM
Yes, agree. The way its done on LED light bars (and formerly on incandescent light bars) is to simply turn off some of the individual lights when toggled. For example, KKK1822 DOT Ambulance specs and I believe also NFPA1901 for fire apparatus requires that when the vehicle is put into neutral or park, and the master brake is applied, an interlock circuit engages which turns off certain forward-facing flashing lights. This is to prevent blinding oncoming drivers if the apparatus is parked in a roadway, especially at night -- and nearly essential for wig-wag headlights. For a small public safety rated flashing LED, it'd have to have that feature and the wiring to power up fewer of the LED's under certain circumstances. I would wager Whelen or another company might actually make something like this, but probably not in the 4-LED small surface-mount variety.

I think the best solution is to again, hook something like this up to a timed relay. The one I ordered I am familiar with from back in the day installing car stereos and alarms and such... it can be set to "latch" for a certain amount of time, then "unlatch" after that time expires. Then, when it sees a loss of power after unlatching (equivalent to releasing the brake(s), next time it "sees" power it'll repeat the process over again.

I have a block of super bright LED's that Marc Parnes sells for radar detectors.  It plugs into the external speaker output of my Beltronics radar detector.  The volume control does vary the brightness of the LED's.  These operate on 5 volts btw.  I may run to Radio Shack if I have time tomorrow and do some experimenting.  I do agree that LED's are not considered easily dimmable, but the guy I work with says they discovered it working with some engineers for a very large company who shall remain nameless that we sell them to.  He has no idea what types can and can't be as the products we sell are very specialized industrial fixtures and are early in their product life cycle.
Title: Re: C14 aftermarket LED brake light / ???
Post by: jjsC6 on June 14, 2012, 12:24:34 PM
Okay, true to my word, I tried a dimmer on a super bright LED today.  I had the LED laying around the garage (yes, I'm weird like that).  I ran down to Fry's and bought a potentiometer (which is also where I bought the LED a while back).  As a disclaimer, I have been in the electrical industry all my life on the sales, marketing and sales management end, but I am not an engineer.  I understand basic electricity, I know ohms law, and I frequently do wiring around the house.

I ran the hot wire off my motorcycle battery, through the dimmer (easier than trying to remember how to spell potentiometer) and to the LED, grounded back to the battery.  The dimmer did a fine job of dimming the light.  Not being an engineer, I did not know which dimmer to buy - rated in different Ohms that were available.  After experimenting, this one definitely dims it and does it in a very linear fashion, but next time I would probably buy one with a higher max resistance.

My disclaimer is that I don't know if different LED's respond differently, but this responded well enough that if Steve wants to try messing with either a dimmer or an inline resistor that there is very little money involved to try it, and I give it a good chance of working.

Steve, the one thing I am curious about is whether dimming would work if you have it set to a pattern that is not continuously on.  The unit you bought obviously has some sort of electronic circuitry that allows you to change the pattern.  I can see as how that might effect the ability to dim it, but I have no way of knowing without testing it.

I received my pulse timer relay in the mail today, I'm going to install it tomorrow. I'll get a few pics to show y'all what I did, if you're interested. Grabbed the installation paper from online (the one that came in the box is WAY too small a print for my eyes to see)... so I'll fuss with it then. It'll be a quick change from the relay I have in there.

Oh yes there most certainly is.  High beams can and will blind and/or dazzle oncoming traffic in the daytime which is not only annoying, but also dangerous.  It makes it MUCH harder to tell where the bike is/how far it is away, or which lane it is in.  This tends to throw away many possible safety gains.

If you want more front visibility, I think the best thing to do is to add properly adjusted, wide-angle driving/running lamps as far away from the headlights as possible.  And preferably yellow for additional contrast.  This provides more frontal area, a bigger apparent vehicle size, and more geometric clues for distance calculation.  Plus it helps not only in the day, but also at night, and for more angles/situations.

But you may believe what you like.

I've taken three MSF courses and every single one of the instructors said that same thing, use your high beams during the day for added visibility. The MSF videos say the same thing. That's what I do and I've never had any issues related to this.

You're right, we'll agree to disagree on this subject.

Daytime highbeam headlight use is the visual equivalent of loud pipes save lives.  There is some small portion of truth of getting attention, no evidence of actual accident reduction, while being annoying and discourteous to others.  It is a position often fanatically held by those who do it, while often astounding those who don't practice it with the rudeness/inconsideration involved. 

If you want to be the life of the party, shine a flashlight in the eyes of your friends and give them a blast with an air horn.  Or maybe just do it walking down the sidewalk so nobody will bump into you.  Yep, that's the way to build good will and better friendships.  Or not.

As maxtog noted, daytime highbeam use makes distance and speed perception of the motorcycle more difficult.  It is also illegal in some states.  The wording is a bit vague in AZ, but it appears to be illegal w/in 500 feet of oncoming traffic and 200 feet of followed traffic.

Here's an interesting link on this topic of high-beams:

Specifically, the second bullet point about mid-page:

Using the high beam of a motorcycle’s headlight during the day also helps to prevent violations of the motorcyclist’s right-of-way (Hurt, 1981).

Speaking of conspicuity (this page section title), here's yet another interesting tidbit about motion induced blindness (from the MSF website):

http://www.msf-usa.org/motion.html (http://www.msf-usa.org/motion.html)

Finally, here's an interesting video from the UK, I believe, regarding visibility and focal aspects of a motorcycle approaching a 4-wheeled vehicle which isn't moving (i.e. preparing to pull out into the roadway):

Oh, and what I forgot to add -- think about the "camouflage" theory in the video, relative to a single bike... and then, how about group riding in a nice tight, but safe formation? This theoretically would increase the "size" of the visual package from other drivers perspective and may be why, at least in my experience, group riding seems to make us all more visible.

I installed my DEI (Directed Electronics Inc.) pulse timer relay this morning. Works great. With the brakes held on, the OE brake light stays constant, my trunk lights stay lit constant also, and the super bright Whelen flasher stays on about 6-7 seconds. I can turn it longer or shorter too.

This way, sitting still where I have to keep the brake on or in other scenarios where the brakes may be slightly applied enough to trigger the lights for a longer period, the super bright light won't stay flashing constantly.

Upon release and reapplication of the brakes the cycle starts over again.

Yep that is the same ONLY reference I was ever able to find, one person's position back in 1981- Hurt.  Hardly scientific, never cross-examined, and 31 years old.  Overall, not impressive.

I've never heard of the MSF endorsing loud pipes but I have heard of them endorsing use of your high beams during the day. As I told Max, I don't take everything that the MSF says as gospel but for me, this one makes sense. I certainly don't consider myself fanatical about it and I won't try to convince anyone else to use their high beams during the day, to each their own.

As for being the life of the party? I don't know how you party Clyde but flashlights and air horns are seldom used at any parties that I attend. Maybe that's why I rarely get invited? I'll try to remember to bring my own next time and see how that goes.

I guess I make a poor ambassador for the motorcycle community after all. Oh the humanity.

I've been using that lil weave when approaching someone that I feel either, hasn't seen me on the bike, or that may be thinking of pulling out in front of me, ever since I watched that video. The weave seems to help get their attention, that and my high beams.    ;)

With regards to the 81 hurt report and, high beam,  I dont recall any motorcycle back then that had much more than a decent light up front. Certainly nothign out there liek the c14 light system.  The first bike that was nto scary to ride at night...well, within reasonable speeds, anyway.

Exactly.  I didn't even have a driver's license in 1981!  Cars back then had incredibly dim and poor quality headlights.  They were still using sealed beam.  Halogen wouldn't even come on the scene for several years later.  And general bike technology was even worse.  I would estimate a typical 1981 bike would have less than 1/5th the light output of the Concours 14.

I've never been blinded or even bothered by anyone's brights on during the day. Even raised SUVs right behind me in my
mirrors. There just isn't enough contrast during the day for it to be a problem. Maybe my eyes are different? I've had more trouble
with the sun reflecting off of various things.

I like the idea of noticing the background movement in the British video, a good point. I don't think I'll be weaving when I'm
in a situation like that, but maybe a few flash-to-pass hits on the switch. I have the Denali lights mounted low on the front
wheel, it sure would be nice if I could just push a button and make those alternate pulse like a headlight modulator would.

Oh my, we are a bit off topic (C14 aftermarket LED brake light / ? )  :offtopic: Sorry, for the record, I didn't start it.
Just to technically stay on topic I'll self promote my old post: http://www.zggtr.org/index.php?topic=1071.msg30644#msg30644 (http://www.zggtr.org/index.php?topic=1071.msg30644#msg30644)    ::)

I've never been blinded or even bothered by anyone's brights on during the day. Maybe my eyes are different?
Oh yes, that is quite possible.  I have noticed as my eyes get older, it is easier to be dazzled or "blinded" by bright lights- be it sun reflections or highbeam lights- day or night; especially at night, of course.

I don't think that would be a good idea.  Flashing is generally regarded as a universal sign that you are yielding your right-of-way or passing.  I bet the weaving is more effective, if not strange :)

I like that idea much more.

Please! Will SOMEONE WHO WANTS TO DISCUSS RUNNING YOUR HIGH BEAMS OR NOT. Please start a thread in The Open section. PLEASE!

Now, for the ones who WANT TO STAY ON TOPIC. What has worked for the ones that have LED taillights?

I installed my DEI (Directed Electronics Inc.) pulse timer relay this morning. Works great. With the brakes held on, the OE brake light stays constant, my trunk lights stay lit constant also, and the super bright Whelen flasher stays on about 6-7 seconds. I can turn it longer or shorter too.

This way, sitting still where I have to keep the brake on or in other scenarios where the brakes may be slightly applied enough to trigger the lights for a longer period, the super bright light won't stay flashing constantly.

Upon release and reapplication of the brakes the cycle starts over again.

If anyone needs the wiring diagram in regards to how I hooked this up, I'll post it or send it, their choice; and I can explain how I did it.

I don't mind continuing the hijack.  Besides, one could argue that the subject is "safety lighting - how much is too much".  :)  If you go through the actual Hurt Report (almost 500 pages, and a lot of it is pretty dry), there is no actual recommendation of daytime highbeam headlamp use.  They do recognize that there is an argument for highbeam use, but they did not study or quantify it, nor did they conclude that it is/was a good idea.  At the time of the study, bikes had only recently been required to have headlamps lit at all times from the factory, so they were comparing headlamp use vs non-use only.

The highbeam use advocates drew the conclusion that if a headlight helps make the bike visible, a highbeam must make it more visible.  It many ways, that seems reasonable, but there are no studies, reports nor statistics to back that conclusion.  There is evidence that it is not always so much of a question of whether the bike was seen, but rather a question of whether the distance and approach speed were correctly estimated by the observing traffic.  Unfortunately, highbeams can and do make those calculations more difficult, and may increase the risks rather than reducing them.

Again, this is relevant particularly because Steve started this thread asking for options to reduce the offensiveness of his super-bright rear safety light.  It is good to be visible, but there is a limit beyond which more harm than benefit is achieved.  This is a simple concept.  Drawing that line between enough of a good thing and too much (morphing the good thing into a bad thing) is something each of us is called to do on a regular basis in a wide variety of situations.

my topic is "back brake LED bright, nothing to do with any other light.

of course we could really get a great drama thread going with front lights high beam or not, flashing or not, etc  :D
