Abstract: A controller includes a voltage detection terminal, a current detection terminal and a voltage sensing terminal. The voltage detection terminal senses a second output voltage. The current detection terminal senses a current of a light source. The second output voltage is sensed prior to the current of the light source.

First location data including locations for the vehicle is received, from a first gateway device located on the vehicle. Second location data are received from second gateway devices, where each one of the second gateway devices is on a respective trailer from a set of trailers and each second location data includes locations for the respective trailer. For each trailer that meet a set of criteria, a score is calculated based at least in part on the first location data and the second location data of the trailer, where the score estimates a measure of association of the trailer with the vehicle. A first trailer is selected, based on the scores of the trailers, to be associated with the vehicle indicating that the first trailer is physically coupled with the vehicle.
