VEHICLE LIGHT CONTROLLER
First Claim
1. An automatic vehicle light controller comprising:
- a microprocessor inside an vehicle body; and
an infrared sensor,wherein the microprocessor is connected to a power supply, a regulator, a light relay, a turn light switch, headlights, an infrared sensor and a vehicle electronic lock through one or more wires, and when infrared intensity is weak and detected by the infrared sensor, the infrared sensor generates a feedback signal to the microprocessor to turn on the headlights, and when infrared intensity reaches a predetermined level, the infrared sensor generates another feedback signal to the microprocessor to shut off the headlights.

Abstract
A vehicle light controller that uses a microprocessor to automatically control the headlights is disclosed. An infrared sensor is installed in the vehicle to detect feedback signal to transmit the signal to the microprocessor. When the weather is cloudy, dark or rainy, the headlights can be automatically turned on to prevent car accidents and further enhance the safety and convenience when the user drives the vehicle. When infrared intensity is weak, the infrared sensor is triggered to provide a feedback signal to the microprocessor to turn on the headlights. When the infrared intensity reaches a predetermined level, the feedback signal is sent to the microprocessor to shut off the headlights. A monitoring circuit can shut off the power supply when the microprocessor does not work properly or transmit wrong feedback signals to prevent the headlights from being turned on abnormally and prevent the power supply from being uncontrollably drained.
