What causes this?

Ive been going thourgh my shots of the Rally of SA over the week and have found a couple of shots with a strange relfection, on the right hand side of the car there seems to be a reflection from the lights, does anyone know what would cause this?
Was using a d200 for the second day with a 70-200 plus a hoya 77mm uv filter, this was shot at 1/800th, iso200 and f9
