Just say no to goofy looking headlights on air cooled 911s & 964s.
Just say no to LED bulb retrofits in Halogen housings.
Just say yes to headlight relays as their installation is a best practice on these cars.
For cars running sugar scoops, the Holley / Morimoto Classic White RetroBright LED headlights are the best solution that I've found. It's a modern engineered LED lighting solution, with a period correct look (especially the Classic White versions).

For those of you that want to run pavement melting wattage H1s or H4s in your '74 - '89, JWest offers a High Power Relay set.
For my ~5% nighttime driving use case, this traditional Euro H4 setup, with JWest standard relays and standard 55/60 watt bulbs is simple, elegant and gets the job done.
