I dont have projectors, buti do have clear headlights and they improve night time visibility a great deal. They are holding up pretty well too. I honestly like these much better than the projectors
I have projector headlights and they are great! They have been on my car for only 6 months so they haven't had a chance to yellow. They are really bright at the moment, but I am planning on doing a light bulb swap to the 9006 super bright halogens (one of these days). I will try to get a pic of my car on here.
That pic for my avatar is an old one before a few things were done.
