If the trailer is more than 5 metres long you should have side retro reflectors every 3 metres. Parking on the road in darkness It is strongly recommended to have stop lamps and indicators fitted to the trailer and have them working regardless of the legal requirements. There are many accidents each year with drivers overtaking tractors failing to indicate when a trailer is about to turn right. There isn't a requirement to have stop lamps (brake lights) fitted on trailers but these should be fitted if obligatory stop lamps on the tractor are obscured. Vehicles built after 1986 and which travel over 15mph require dipped headlights, indicators and hazard warning lights.

Trailers need to have red rear position lights (tail lights), they should also have two red rear reflectors and a number plate light. If equipment covers the lights i.e. mounted or trailed equipment, then extra lights must be fitted to the equipment. Amber beacons are required on any vehicle and trailers if they cannot exceed 25mph and are driven on an unrestricted dual carriageway. Motor vehicles should not be left standing on the road at any time between sunset and sunrise unless: Using work lights at the front of the vehicle can dazzle other motorists even when they are pointed down as they are in such a high position; it is also an offence because they are in the wrong position for road use.These will normally have been taken into consideration by the tractor manufacturer, but if you are unsure or you have modified the vehicle in some way or you need to fit lights to compensate for covered or obscured lights on the towing vehicle you can call NFU CallFirst on 0370 845 8458.
