yea chp3 article 16, but I looked and did not see any info on color of the headlights. You might want to give your local dept. a call, and ask what is legal and if they can fax, e-mail, or mail you a copy of the exact code that states the law. Here in California it is illegal to have yellow or blue headlights specifically, and illegal to have any red or blue forward facing lights no matter where they are. Amongst other things, but just to give an idea. I try to study up on laws like this in my state that way if I get pulled over and ticketed for something I can fight it in court. For example, it is NOT illegal in California to have underbody Neon, LEDs, Cathodes, etc. AS LONG AS the tube can not be seen while driving and can not be blue or red. I had the CVC number in my Sidekick in the glove because I had green neon underneath her. Do some research on that sight, and you will be suprised with some of the things that are perfectly legal.
Here is a nice lil link for all those who live in CA, these are some of the most common mods that people in CA do, so the CA DMV has kindly put this lil page together.
