CAN-BUS LIGHTING ADAPTOR

An adaptor for connecting an LED lighting unit to a vehicle CAN-bus. The adaptor has a connector connectable to a corresponding connector on a vehicle, to receive a lighting current from the CAN-bus of the vehicle. A wireless power transmitter of the adaptor wirelessly transmits power to the LED lighting unit at a first level, typically suited to LED operation. The adaptor further includes one or more resistors connected between the connector and transmitter and arranged to draw power from the connector at a second power level higher than the first power level, which second power level is suitably equivalent to that for halogen or filament lighting.
