Frequently asked questions

Work or ploughing lamps are fitted to the back of agricultural tractors and self-propelled machinery (as shown) to give extra visibility when working on the farm.

Work or ploughing lamps may be used in your own private area i.e. field, farmyard etc. but it is illegal to use them on the public road so they must be switched off beforehand.

Road traffic regulations ban the use of white lights to the rear of any vehicle in a public place. In times of darkness, it can confuse motorists into thinking that a vehicle is approaching. Only red and amber lighting should appear on the back of a vehicle, not white lamps. In addition, these work lamps are highly powered which can cause other road users to be temporarily blinded which is a serious road safety concern.

For further information on the correct operation of agricultural machinery including lighting, Download and read our Revised Standards for Agricultural Vehicles.
