Bought these off eBay a few days ago but came across another set I want to buy. These are the SAE M Motorcycle versions and are DOT approved. Perfect 7'' housing to get rid of the sealed beams for a Miata/Jeep/Nissan conversion.
Team these up with a nice pair of Osram/Hella bulbs, and they'll throw some very good light in the proper cut off zones.
Review and comparison:
Bosch H4 Lighting
These do not come with bulbs are are BRAND new in packaging.
Price: $55
