I spent 6 years stationed in Germany and these are German Parking lights. In Germany the streets are very narrow in most villages and you have to park with 2 wheels on the curb/sidewalk. It's the law that after dark the side of the car that's in the street must be lighted. So if your right hand wheels are on the curb, your left hand parking lights must be on and vise versa. Needless to say this is just for short term and not for overnight.
