reverse lights

[pug306driver]

they work but are very poor, checked bulbs and they are ok, not black and are 21watt and work ( seem them work in reflection ) .....the lens is coloured red and looks standard....is this CORRECT, as I cant see a dam thing in the dark when reversing............if all ok ( red coloured as standard ) I will fit some extra reverse lights.......is there a white ( clear ) "fog light unit" for the LHS as the one in there has no bulb hole !!

thanks....
