I installed an Autometer ultra-lite speedo and tach in my car a while back and then I installed electroluminescent faces on my stock gauges that fairly closely matched the look of the Autometer gauges (at least during the day). The problem was they looked very different at night. To make it even worse I just installed a stereo with blue lights, and my wife and I decided that I needed to make my Autometer's light up blue as well.
I searched around and found out that Autometer sold these little blue condom looking caps to make their lights shine blue. I bought these and installed them, but they looked more green than blue, and just kinda overall looked bad (the carpet dash pad will be replaced soon).
Unsatisfied I kept searching around until I found out that you can install blue LED lights. Autometer sells those as well, but the want like $12 a piece. I kept looking around and finally figured out I could buy the LED lights I needed on eBay for about $2 a piece.
Well I installed them tonight, and now I'm very happy with the results. What do you think?
