Vehicle light control system for automotive vehicles
First Claim
1. A vehicle light control system comprising a first and a second switching device, said first switching device being in a normally conductive state, said second switching device being in a normally non-conductive state, said first switching device having an input connection securable to a terminal of an alternator of said automobile vehicle, said alternator being connected to a car battery supply and providing a supply voltage when an engine of said vehicle is operated, said first switching device further having an output connection connected to said second switching device to change the operating state thereof when said supply voltage is present on said input connection, said second switching circuit having a low beam connection to which said car battery supply voltage is connected and fed to a low beam filament of headlights of said vehicle, said first switching device having a third connection securable to a vehicle headlight switch high beam position so that when said headlight switch is placed to said high beam position said first switching device is placed in a non-conductive state which in turn automatically places said second switching device in a non-conductive state to cut off said supply voltage to said low beam connection.

Abstract
A vehicle light control system for controlling the low beam of headlights of a vehicle. The system comprises a first and a second switching device with the first switching device being in a normally conductive state and the second device being in a normally non-conductive state. The first switching device is connected to the alternator of a vehicle to tap a supply voltage therefrom. The second conductive device is condition by the first conductive device and is also connected to a supply voltage to feed the low beams of the headlights when conditioned to do so by the first switching device. The headlight switch of the vehicle when switched on the high beams cuts off the first switching device and the supply voltage to the low beams. The supply voltage fed to the low beams is further reduced whereby not to subject the low beams to full intensity whereby to prolong their life span.
