I am trying to find out somewhere where I can find out what the different colours are for and if anyone has them to tell me how they work?
I am in Russia so we have the European standards - this means red fog lights in the rear bumper.
I am looking to replace the rear bumper with LoD or PSC. I think about getting one or two red to serve as the fog lights in the holes provided. Would be great if they served as backup lights as well.

While looking I see many colour choices (or for non Canadians "color"). RI does not say what the colours are for.
White - easy to understand
Amber - front Fog lights - any other purpose?
Red - rear fog lights - any other purpose?
Blue - ?????
Green - ????

Does anyone have any of the Coloured ones? I guess since they make them there must be demand.
If so do they work as back up lights as well?

Thanks
