Samling: H4 HALOGEN REFLECTOR HEADLIGHTS

AC joins the 21st Century!

Our focus on headlights for the past 15 years has been restoring originals - until now. We have added two H4's currently being produced to or catalog.

LED headlights are gaining rapidly in popularity, but the most common headlights used on air cooled Porsches today are H4 halogen reflector lamps. Originally produced by Bosch who no longer produce them, they are currently manufacturers by a number of companies. We have chosen the following two to add to the AC Catalog:

PRODUCT INFORMATION

Magneti Marelli H4's are manufactured only for Porsche and with the absence of Bosch most consider them to be the industry standard H4 headlights.

PRODUCT INFORMATION

A Short History of H4's

Sealed beams were mandated by DOT in the United States until the early 90's and all cars delivered to the U.S. were equipped with them. Named H5's or, more commonly "sugar scoops", the lights were widely unpopular both for their looks and their pitiful lighting ability. There are probably more sugar scoop parts in landfills around the U.S. than any other Porsche part. They were replaced with a variety of headlights, most commonly by the reflector lamps using H4 halogen bulbs produced by Bosch and called simply "H4's".

Never Use LED bulbs in Reflector Headlights

Please don't try to "upgrade" your reflector headlights with LED bulbs. You won't see better and you may blind on-coming drivers. Supporting Information.
