I just wanted to re-new this thread, find out if more forum members can remark about aftermarket headlights. Anybody use CAPA (cerrified) lights? CAPA (Certified Auto Parts Association) ..autobody replacement parts means they've been certified pretty darn close to the OEM and suitable for bodyshop insurance crash replacement. Experience tells me such parts usually fit well. Sometimes they look and fit great, sometimes less so, but generally the quality is better than the lower priced aftermarket stuff. But of course not 'quite' up to OEM ..but pretty darn close. I've used CAPA certified headlights on other vehicles in the past, some with great results, some so-so.
I'm leaning towards buying a new set from GM, which I will probably do. Problem with my existing headlights is the plastic has a bunch of cracks in them (have for a couple years now) ...and they're the kind of cracks that go all the way through the plastic. Plus, they're a little hazy and yellow-ish ...and the fact they don't 'cast' well (and I live in a rural area with a lot of deer so I want good lighting). It's time for new lights.
