Apparently, a LOT of people (in fact, most that I've heard from) who order these headlights, get a pair without the deflectors in them. That small silver dome that sits in front of the light bulb is the deflector, and it helps make your headlight pattern better (as I understand it).
I'm considering purchasing a set of these myself, but I want to wait until I paint my car before I do. I also want to make sure I get a set with the deflectors in them.
