Bosch H1's are one of the most fascinating early headlights used on Porsches. The H1 halogen bulb was introduced in 1967 and Porsche used H1's on RoW (rest of world) delivered cars from then through most of 1972 when H4's were introduced.

Basically a clever Rube Goldberg device, H1's were developed to enable the use of the H1 halogen lens. Since it had only one filament it was necessary to use two bulbs, one for low beam and one for high beam. This necessitated the use of two reflectors and of course the ability to adjust them both.

Restoration of Bosch H1 Headlights

The restoration process at Audette Collection starts with your cores or high quality original Bosch H1 cores and finishes with concours level headlamps. Reflectors are silver plated (silver, used in the early day - now it's mostly aluminum - is the most reflective practical plating).

 

Reflectance Comparison
Silver: .95512 = 100%
Aluminum: .91320 = 95.6%
Chrome: .60604 = 63.5%

 

 

Next comes assembly using the highest quality parts. The end result is suitable for high level concours cars which have won at notable events, such as the Concours on the Avenue in Carmel, California.
