I have a Depo headlight and a depo fog light. I'm actually very satisfied (and somewhat impressed) with the quality of the product.
HOWEVER, I've heard some less-than-flattering things about Depo headlights that have been used for HID retrofits (or anything involving baking the headlights). I've heard of the lenses forming small hairline, spiderweb-like cracks. This is across different makes and models (Subaru, BMW, Toyota, etc).
I'm afraid to even try on my Depo lights. I'd try to find used OEM if I were going to do a retrofit.
