I also had put the Silver star bulbs in mine. I switch to them in my car because I drove to work at night. That didn't help much. So what I found was they were way out of adjustment. But that is what was bad on the housings. I couldn't adjust them. When I put the new housings in and got them adjusted, they were as good as my car at night. They were actually cross eyed. The left was shining on the right shoulder and the right on the center line. The new fixtures fixed me right up.
