honestly dude,
i got a set of crystal clears off ebay & my opinion of them is the same as other items in this class.they fit like crap & will require a bodyman to line up the gaps & make them look straight in the grill.the backs have screw-type bulb retainers instead of twist-in slot-type.they're ok if you don't mind all that work,but i'm gonna skip them.seems these never quite live up to stock oem quality,no matter who makes them.these tahoes come with nice sylvania headlight housings & i polished mine up with mother's gold plastic polish & threw some sylvania silverstar ultra bulbs & they look alot better.i used a nokyia hyper-yellow high beam for a more functional high-beam in rain & snow too:yesnod:
