Big thanks to Scott (vendor Scoot)!
Just spent a relaxing Saturday putting in my Varta 35W Yellow Fog Light bulbs
My SL has two different headlight doors one is "AC" new BOSCH OEM with clear lower lens; and one is "AN" the clear lower lens with large inner amber-lens.
Back in '91 (when I was broke) and didnt know the difference I got the "AN" amber lens unit for $75 from a junk yard (Potomac German Auto) and popped out the orange lens and swapped out the old inner reflector units and sanded and painted the reflector with "chrome paint".
Well, 25 years its still "OK"; although the internals are quite weathered, as it was parked in a car port for 15yrs, before restoration. Also notice the fit of the "AN" amber lens unit is very tight for a 250SL v. the "AC" which has a smaller/tapered plastic cover with angled rear to clear the screw tab.
The new "AC" was immaculate even after 10 years (stored inside) and reflectors were mirror like.
I ordered 2 bulbs from Scoot and they were NOS and crystal clear deep yellow bulbs.
I easily popped them in and they gave the lower reflector a very vintage racing/rallye style Yellow hue from just daylight reflecting thru.
Once installed, they give off a perfect cool YELLOW (not gold or amber) very bright light that illuminated the entire lower reflector housing.
Highy recommend as a tasteful / reversible mod that takes 1hr to swap.
I having been searching for 20+ years for a French Yellow bulb after seeing a photo of Yule Brenner standing next to a 300 SL Roadster in St. Tropez with a yellow flog-bulb in headight-unit.
Bravo Scott!!
