Abstract
A system is described for causing automatic activation of vehicle low beam headlamps. Three voltage sensors, including a voltage slope detector for sensing engine start-up, cause activation whenever the engine is running. Separate master and slave modules allow for retrofit installation using the vehicle's existing wiring harness. Cables and cable connectors connect the system directly to the headlamp wiring harness, headlamp base, and vehicle battery without the need for splicing. The system can be bypassed or overridden by operation of the vehicle's standard headlamp switch.
