So I really dig clear reflector style housings, tried to ignore that I knew they were gonna be crap. Got some from eBay (VIPMOTOZ) and they looked OK at first. Some of y'all have seen me post here in the past that I later noticed after installing HID's that the headlights had a weird smoky look to the lens, that appeared to be on the inside. Also the park lights didn't fit as well as I hoped; I had to space the retaining clip by jamming a screw into it on each side to keep them from just falling out of the grille. That worked fine but just irritated me a bit.
A few months later I noticed the passenger side park light fogging up all the time, fairly typical. It just finally began flaking the chrome off the reflector a couple weeks ago. Then all of a sudden without any history of fogging up, the driver's side park light fogged up and almost instantly began flaking the chrome!
At the same time I noticed a big spot cracking/peeling in the clearcoat on the driver's side headlight...yeah, the foggy look was really badly applied clearcoat. The lens is normal appearing underneath. They'd look fine once the clear is removed (and re-done so the lenses would last.)
But ya know what? Screw this aftermarket junk. I just ordered all OEM GM lenses on Amazon. Cost me $340 total for all 4 but that's cheaper than most places for OEM. Can't have my truck looking like ass because of some clapped-out lenses that aren't but 1.5 years old.
