The use of all lighting fitted vehicles in the UK is covered by "The Road Vehicles Lighting Regulations 1989."  In summary; amber beacons should only be used where it is necessary to warn other road users of a hazard. Beacons  should only be used when the vehicle is stationary or being driven slowly.
