A friend of mine back in Montana put some cheap-o conversion in his 92 Vette. Hard as crap to put those in and one of the worst patterns I've ever seen (probly 2nd to my 96 Contour that was missing half the lens/reflector after an accident
). But they were bright as hell, so he didn't care.
Back before Silverstars, I put a set of Cool Blue sealed beams in my low beams of my 84 Monte Carlo SS. They were WAY better than stock. I used to not be able to tell if my lights were on in the city, but I could see the pattern like it was pitch black... I assume they worked so well b/c they got to design the lens/reflector and position the light in the perfect spot.
EDIT: found the housings on
Ebay. Notice how the "projector" part doesn't work since the top of the H4 lights are painted.
