If you are an owner who values originality for your vintage Porsche headlights are a good place to start as they are so visible on the car. Real restored original parts always cost more but they add to the authenticity of the car. Important to some, not to others.
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 bulb. 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 includes the following steps:
- Reflectors – stripped, copper plated, nickel plated, polished, followed by vapor deposited aluminum plating, silica layer – Why aluminum?
- Housings – media blasted and powder coated
- Lenses – new with correct Bosch lettering
- GE Nighthawk 9003 +120% bulbs
- Lens Gaskets – new
- Chrome Trim Rings – new**
- Adjustment Screws – mounted with nylon lock nuts for easy removal
- Fender Mounting Screws
- Fender Mounting Gaskets
