Hi, maybe someone here can help me. I have a problem finding spareparts for my quad headlights...they are not Morette quads but from the following company, it is written on the back of them :

GFL Sportsline Dobbeltsheinwerfer
15.51.10.L.88 and 15.51.10.R.88
7332 Eislingen

They look like this.....





I have tried to contact different companies and searched on the internet...but no luck
