Rule 43

You MUST follow the same rules about using lights, indicators and horns as for other road vehicles, if your vehicle is fitted with them. At night, lights MUST be used. Be aware that other road users may not see you and you should make yourself more visible – even in the daytime and also at dusk – by, for instance, wearing a reflective jacket or reflective strips on the back of the vehicle.
