Patent ID: 6936969

Claim:
A secondary headlight system for detecting and compensating for failure of an automotive vehicle's low beam headlight, the system comprising: (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.
