I love the look of mine but need to send them back
I don't know if they are real "Dectane" or not. Mine came from a seller "Crazy The God", and seem to have been made somewhere like Taiwan, NOT Germany

Are those your issues as well? Was it the lights, or do they cars just not "accept" after market lights?
