This is what Bekkers just told me:
Apparently Bekkers buys from the manufacturer of the lights rather than the dealer. The fronts are OE from BMW, but the rears were purchased right from the light manu. I checked the stamps on the lights and rears have the same stamps as the fronts except the fronts have the Roundel. This proves they are the same makes just not stamped for BMW OE. According to Bekkers they are OEM (Original Equipment Manufacturer). Both built on the same assembly line just one is sent out to BMW and stamped, and the others are sold to other dealers, not stamped for BMW. THis is how they are able to sell them cheaper. They said if I had any prob's to give them a call. They have great Customer Service, John was excellent, and prompt shipping. I will be using them for more stuff if possible. Can't wait to throw them on my ride!!!! I'm waiting at the port of exit for my boat!!
