Abstract
A power supply control circuit for selectively supplying electrical power to either a first high-mount lamp installed on a detachable body component of an automotive vehicle body or a second high-mount lamp installed on a main body component thereof has a relay and two diodes. The relay establishes the communication between the second high-mount lamp and a power source in response to turning ON of a brake switch when the detachable body component is opened or removed from the main component and blocks the communication when it is closed. In this circuit, the power source applies voltage to relay coil via an ignition switch and one of the diodes or via the brake switch and the other of the diodes, so as to prevent electricity from continuously passing through the relay coil when the detachable body component is opened or removed from the vehicle body for a long time.
