So I had an idea and had a couple extra LED's and thought this might be fun to try. I gutted the housings of two regular incandescent light's and put in an LED with a resistor. I must say that it turned out pretty cool. The problem is that the light isn't dispersed enough to cover the whole gauge. Need to find some different LED's. The pictures didn't come out that well but here they are anyways. Maybe if I had a better camera.
