Thanks guys. I was gonna remove the lower panel, didn't think about removing the spare & looking!!!!
However, Gill at "bettercarlighting", where I bought the parts has offered to replace the units with LED bulbs.
Only problem is these units replace fog & stop lamps in one go, so I now need a "clear" lens to replace the RED fog glass. Any ideas where I can get that from???
I do not get this. Isn't the rear fog light independent, just as the reversing light? I live in Norway, and at least here you can get both white and red LEDs. I have put a white LED in my reversing light, but so far kept the incandescent bulb in the fog light, as LED might be to intense. Two stop lights are combined with driving lights, they will be substituted with red combination LEDs. The third (cyclops) stop light will be substituted with a red non-combined LED. So, red LEDs behind red glasses, white LEDs behind clear glasses. All this is available here, so I guess it would be in Germany too. In any case, here is the Norwegian company: ekstralys.no. Website in Norwegian, but a bit GoogleTranslate could help.
