I kept the white ones in...looks cool. I don't think it is street legal, for the same reason why your break lights need to be red. But I have never been pulled over and if you ever are, just plead stupidity and say "yes officer, first thing when I get home".
Oh, but if you do keep the clear lights I would suggest you replace them with the hyper whites or some shit like that. When I first got mine in and turned on the headlights, the headlights were a briliant white while the bumper lights were off white. Problems been solved.
