1992 500SL, 1988 560SL, 1977 450SL, 1999 E320 4matic
When I bought my almost perfect 1992 500 SL, a new set of right and left headlight lenses and headlight doors from Mercedes came with the car. The previous owner did a complete rear and side light update. The old headlight lenses and doors are discolored and cannot be brought back to a new look like the rest. Can anyone tell me the correct proceedure to do the change as it does appear to me to be time consuming but I'm willing to give it a try..... Thanks everyone in advance.
