BOSCH H4 fluted lenses are fine but they are vertical with a ridge on the top which breaks the perfect silhouette of the 911. The HELLA 4475 and Bosch 4487 lenses were used on early 911's.

As they are very similar in appearance and quality, we use the Hella and Bosch lenses interchangeably depending on availability. You can also choose Bosch H4 lenses with proper Bosch logo's..
