ABSTRACT:
An automated control system for controlling lights and other electrical loads in a motor vehicle is operable with an engine-driven alternator and responsive to the operation of the engine for turning on the load whenever the engine is operating or above a selected engine speed. The vehicle loads are switched on and off automatically by the sensing of alternator output voltage, either alone or in combination with alternator frequency or sensing battery voltage, or both.
