For new vehicles with a Canbus connection, the problem with connecting a trailer or bicycle rack with LED lighting is that the on-board computer of the towing vehicle displays an error message. This Carpoint LED Canbus converter solves malfunctions or other error messages, when used in combination with a car and a trailer or bike carrier with LED lighting. 

The Carpoint Canbus adapter communicates with the Canbus system of the base vehicle. The adapter has two 13-pin plugs and is easy to place between the 13-pin connection of the car and the trailer or bike carrier.
