in my front clear corner and clear rear side marker lens. They send off more of a superwhite but show a tint of fuzzy blue(kind of like flourescent bulbs). It really turns heads. Being that my superwhite fogs w/out glare gaurds are rewired to come on with any or none of the lights on, the Z looks clean with all but the headlights on. Plus it's very cheap to do. If you don't like the look, just put what you had back in. No loss in my opinion.
