HEADWINDS BILLET HEADLIGHT HOUSINGSA must-have for that true custom look. All Headwinds® billet aluminum housings are spun, machined, and internally threaded for a screw-in bezel. Each headlight features smooth, non-wavy surfaces with mirror finishes. The disappearance of the flanges and rivets on the outside of housings make it a showpiece. Lamps and Mounting Posts sold separately.
