A current load circuit provides a predetermined current load on a current load line of an electrical supply system of a vehicle. The current load circuit comprises a switching boost converter 51 charged from the current load line 34 and discharged to a return line 55 of the electrical supply system of the vehicle. A current load control circuit 53 controls the operation of the switching boost converter to maintain a current load on the current load line above a predetermined current during operation of the switching boost converter, such that a portion of the current drawn from the current load line is returned to the return line of the electrical supply system of the vehicle. The current load circuit provides a regulated load for a vehicle electrical system so that a control device of the vehicle correctly detects the presence of an element (e.g. retrofitted LED lighting or trailer braking system) whilst the current load circuit dissipates less power than some conventional circuits.
