Long story short, i have lost a front blinker lense from my BMW. Simple - buy another one. Not so. The fairing has been custom made by the original owner and made to fit around these specific lenses. There is no ID on the lenses other than E4, and i dont think they are BMW - none that i have found anyway. The original BMW indicator set up is completely different. So, if you know what they are from, id appreciate knowing as my bike is now a shed ornament till i can find some. The only clue i can offer is that they were already on there in 1996 when we bought the bike, so they cant be from anything newer than that.
