Towbar wiring often requires relays of various kinds depending on the vehicle in question and the needs of the vehicle and trailer electrical systems. These relays should be fitted by trained towbar technicians who are aware of the implications and understand what each relay does.
In addition, some modern vehicles with CANBus wiring systems can often work havoc with trailer lighting systems when the vehicle system does not recognise the lower current draw of LED lighting systems. TRAILPARTS® can help you to resolve these issues by advising on suitable LED load devices for your trailers, or LED-compatible vehicle towing electrics - please ask for more information!
