I don't think they're street lamps- first of all, the guy said that they were moving, and second, they were flashing different colors.
The guy was in a car, right? Moving, presumably (although on the M25 you can't be sure). On a motorway there's lots of lights - cars, street lights, signs - places beside the road, DIY superstores and the like - plus that part of the M25 goes under the flight paths for Heathrow airport where they make a turn onto approach... I think maybe we should rule out the obvious first before calling for Will Smith.
