Here is what I posted in the past but couldn't find...Be careful which LED bulb version you get. You need an LED that spreads the light out into the dash channel as it was designed for, meaning multiple LEDs on each bulb. If not the visible light will be lower making the gauges hard to see. You will need 5 of the WLED-GX (4 dash and neutral). "X" is whatever color you choose. You will then need one blue, two amber, and a white if you have an aux light device (early models). Check you own bulb count to make sure. Be sure to order this bulb style as it spreads the light out and doesn't just send out a beam. The clock bulb is 74-GHP (mini wedge base in green) if you want to change it (I did). Bergman was the original one to find and test these and then passed it to me when I upgraded my dash. I used the green version of the WLED-G5 (for the green lights, 5 of them to include nuetral) and it is nice and bright, but not annoying. I also ordered a red, blue, warm-white, and two ambers. I even replaced the clock bulb with a green 74-xHP wedge Base LED Bulb. Here are the links:

Green is the best gauge color because it does not cause your pupil to close down as much so they can re-adjust to the road in front of you quicker. White is about the worst. Just food for thought.
