Hey guys, recently got my R33 S1 headlights retrofitted with quad projector headlights complete with white LED ring angel eyes and red demon eyes. I bought a used set of headlights with yellowing lenses for cheap and sent them up to Sydney to be modified by That Headlight Guy. Needless to say, I was very impressed by his work and the results are amazing. He does work on all types and makes of headlights and even headlights that don't come standard with projectors! Very friendly guy to work with, his attention to detail is especially helpful, he will keep you updated throughout the build process and will even offer headlight lens restorations! 5 stars and will recommend to anyone wanting to do any sort of modification and/or restoration to their headlights!
