Thought it was a police car as saw flashing red and blue lights coming behind me at speed when it was dark, I was doing the speed limit and this driver certainly wasn't! it had flashing L.E.D strips in the bumpers and grills front and rear that then changed to various colours as he/she flew past. this car could EASILY be mistaken for an unmarked cop car there is no way the driver of this vehicle does not realise this, and I suspect uses them to get other motorists to slow down and pull over so they can be overtaken. reported.
