I am living in small village in the Mons, Belgium area. I think that the low beam lens are a plastic and have discolored with age. There is a salvage yard at the army base in Baumholder that I am going to check out. The car does not have any fog lights either and I am going to try to add them. It is going to be interesting working on this car. I have already gained a lot of respect for the German engineering that went into the BMWs.
Thanks for your reply,
