Abstract
A power supply circuit for automotive headlamp assemblies includes a switch assembly selectively operable between a first position at which the electrical power is supplied to high-beam valves of the headlamp assemblies, and a second position at which the electrical power is supplied to low-beam valves of the headlamp assemblies. The power supply circuit also includes means for establishing communication between a power source and the low-beam valves at the first position, so as to turn the low-beam valves on whenever the high-beam valves are turned on.
