As opposed to what everyone on here so far has said about quality, I disagree. I ran these lights for YEARS and had no issues with condensation. The outer layer of the plastic on the face of the light DID delaminate after about 2 years, but it didn't affect the light in any way. It was like peeling skin after a sunburn.
people have had issues with the 3 DRL leds burning out, but I didn't have that issue either.
they are cheap. They look cheap. But if you wire up HIDS into them, they put out a MUCH better beam than the stock housings with halogen or HIDS (please don't put HIDS in a stock housing with retrofitting projectors).
Are they as good as an HID projector retrofitted into the stock housings like nisstec sells? no. But they are about 1/3rd the price.
The best thing you can do is just buy the projectors and retrofit them yourself. any idiot can do it. Seriously. I have less than $100 in my projector setup.
