There is a gentleman that is trying to sell me a set locally over the phone. I asked him if they were Bosch and he said they were not Bosch but were aftermarket. He did not mention who the maker was. I was then under the assumption that there may be a handful of makers of these lights and that they may not all be of equal quality. I remember buying a set of clear blinkers for my 300E that were from In-Pro that were definitely not of equal quality as the original Bosch units. I would hate to buy a set of Euros that were poorly made just to save some money.
