Bosch no longer makes H4 headlights and the world is flooded with them by other manufacturers. 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 H4's were introduced in late 1972 and became an immediate favorite. They were used as OEM parts by the Porsche factory for all of their rest of world (RoW) cars until the 993 that was introduced in 1993.
Restoration includes the following steps:
- Reflectors – stripped, copper plated, nickel plated, polished, followed by silver plating
