I have been looking at a few 97 and 98 SL500's. Some have the headlight wipers and some do not. It seems that the ones with Xenon headlights do not. Were they on all 90-02 SL500's or are they not on some, such as a 98 SL500 with Xenons? I thought they were standard on all.

 

When you added Xenon lights the washers were deleted.. So with xenon=No headlight washers.
