section525 they are legal in CA, even if you use them with clear lights.... but you probably will get hassled anyways.... they are legal though, i plan on getting them soon as i get $.... i am also going to carry a code book from DMV with me though.... that way if a cop thinks i violated a law, i can prove him wrong on the site.... the only way they may not be legal, is they don't pass the United State Department of Transportation requirements for reflectors, but no one knows about that anyways.......
