ABSTRACT:
A secondary headlight system for detecting and compensating for failure of an automotive vehicle's low beam headlight, includes:(a) at least one photoresistor;(b) fiberoptics connected to the photoresistor;(c) at least one potentiometer;(d) at least one NPN transistor operably connected to the photoresistor and the potentiometer;(e) at least one switching relay operably connected to the potentiometer and the NPN transistor;(f) at least one power resistor operably connected to the switching relay; and(g) an automatic reset subsystem comprising at least one capacitor and at least one light emitting diode, the light emitting diode being operably connected to the capacitor and the transistor;wherein the secondary headlight system is connected to a power supply of the vehicle, and a low beam headlight of the vehicle, the failure of which is to be detected and compensated for; and wherein when the low beam headlight of the vehicle fails, the secondary headlight system is automatically activated, resulting in illumination of a high beam headlight of the vehicle. A method is also included herein.
