I have black halo headlights that I put on my 2000 Camry. There are also chrome halo headlights.
I got them for a total of $140 for the pair off of Ebay.
All you have to do is wire up the halos to your parking light wire, which is real easy. One of the wires goes to your green with orange stripe wire, and the other wire goes to the ground, which I just put under the bolt under the corner light.
The hardest part was getting the stock corner lights out the first time. Also because they are aftermarket lights they weren't exactly as easy to fit as the original stock ones. I really had to put a lot of pressure on the passenger side light to get the bolt aligned and bolt it down.
Oh before I installed them, I tried to make the adjustment screws on the new lights match the stock ones, and it seems to be just fine.
