Well here is my set up for my driving lights. I ordered them from here
http://www.superbrightleds.com/cgi-bin/store/index.cgi?action=DispPage&Page2Disp=%2Fdrl.html%23drl-cw5. I was looking for bright,and streamline. As you can see there slim.
the relay is NOT included I just tossed it in the pic to compare the size.
There very slim
I'm not going in to the wiring , but it was straight forward. Black to neg on battery and red to power lead on the turn signal.
Here is how I mounted them. I wrapped some tape around the tip over bar just to make the clamps tighter. Most likely an over kill, since these lights are feather lite.
Here is the finished product. Tonight i'll double check the aim, but these two camera shots don't do them justice, these are BRIGHT...
Cheers
Ron
