Headlight adjustment
Towing a trailer can raise the front end of the vehicle enough for the dipped beam to blind other road users. Use the headlight range control to lower the light cone as required. If you do not have headlight range control, the headlights should be adjusted by a qualified workshop. Vehicles with gas discharge bulbs adjust automatically and do not require manual adjustment.
