Most trailers are not equipped with internal lighting, so it’s a good idea to fit dock lights to improve visibility. Otherwise, operatives entering the vehicle from a brightly lit warehouse can struggle to adjust to the change in conditions and may not see potential hazards, causing injury to themselves or potentially damaging goods. The more useful types of lamps are those that are mounted on an arm which pivots at the wall and in the centre. They then can be parked against the wall of the loading bay when not in use.
