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.
