dumb questions time ...about race cars

...folks do one of two things that I know of for coloured lights.

First, you can line the light reflector with colored plastic that they use on the stage. There is a guy in NS that does this for folks...for a price.

For me, I just moved over to HIDs and picked the Kelvin range that gave me blue. Legal and bright. My wife has the same HIDs but hers are white. Yellow is available too I think..

I do it because it really matches my car and makes it stand out..
