'tezzas on a Z? oh boy. coupla points here, some serious and some not so serious.
1: there is a way to fix condensation on the INSIDE of the headlight, remove two bulbs, let them stay out over night, that condenstation will evaporate out. (this same thing happened to my integra's headlights)
2: I'm not going to lecture you on your choice of tails, but at least look into OEM options I.E. clear JDM lights, or if you don't have 'em, 06+ tails. tezzas belong in one place, and it's not your car.
