From Porsche Club of America, upgrading headlights with LED units.
"Air-cooled Porsche 911 owners from 1964-1994 are faced with several options when it comes to headlights. Aside from replacing a blown bulb for your stock H5 headlights or sourcing a set of European H4s, there are several companies who offer modern LED headlights with superior lighting. In this video, we install LED headlights from Flat 6 Illumination, Audette Collection, and 9Eleven and compare them to the stock H5 lamps"
