[The Dark One]

the red light is a fog light, as often seen on imports here in the US. single reverse lamp isnt that odd, really, but can throw some people off. rear fog lights are always driver-side only, so as to not be confused with brake lights. it is possible, though illegal, on many cars to simply add a bulb to the other side also, so they are symmetrical. I actually got pulled over once in my Volvo because the cop thought i had a brake light out when my single fog light was on... dumb cops need to learn about cars!!
