krwaxbz, thanks for the clarification that repeaters didnt start on the 280Sl models till 1969. I checked the inside of the fenders for evidence of holes for lights... none.
rwmastel, I was referencing Laurence Meredith's book, "ORIGINAL MERCEDES SL", Page 73, 'To meet safety legislation, American 250SLs were fitted with additioanl rectangular side reflectors on the front and rear wings. These reflectors were replaced on the 280SL by indicator repeaters...' It doesnt specify which year 280SL the change took place.
Fabrice, I checked the data plate in the motor bay and it reads 491, thus a US model as you suggest.
LFrank, as a personal preference for aethetic and safety, I desire the side repeaters, especially when they alternate with the front/headlight enclosed blinkers/signals. It feels more European, and by purpose more effective in actually signaling my intentions to other motorists. I agree that the Euro headlights are more attractive and true to the spirit... I WILL have them one day.
krwaxbz, I checked out the site for Danial Stern Lighting and will likely adopt their recommendation for "making" side wing repeaters.
Thanks all for the input/clarification... repeat on!
