I have been driving a C5 Tourer since April 2014, I am mostly satisfied, but I get annoyed about a little bit: the rear lights are so weak that the reverse driving, especially if you don’t turn around, but use the mirrors, comes close to a blind flight. You can hardly see anything. Is there the (legal) possibility to change the illuminants here and use stronger ones? I don’t need the tip, I should just turn around: First of all, it doesn’t get brighter, i.e. otens I just feel safer over the mirrors. I also know that the lights should officially only show the reverse driving to others, with other cars (e.g. Audi A4 8k) I could still see and navigate clearly better. Please use the thread to help me with lighting technology and make no reverse driving philosophy thread out of it. 😉
