Headlights
Me personally I would go with the all crystal look. I am always customizing cars and trucks. Its just when I see someone put the crystal headlights and not the others it just doesn't look right. Now when all of them are done to me it gives it a more aggressive look to it. I have a 2001 Toyota Celica and the driver side headlight is always fading and all i do to remedy that is if it is really bad I will sand it with very fine wet dry sandpaper(with water of course) and then use Mcguires cleaner wax to bring out the clearness of it again. I always hit the headligths with that same cleaner wax when I am polishing the car to help protect it and keep it looking "new". I hope this helps you out.
