AUTOMATIC HEAD LIGHT CONTROL is a light device is automatically tuned off when a driver do not step on the accelerator in a case that a vehicle stop. The present invention comprises an illumination sensor, an illumination controller, an illumination selector, an amplifier, a taillight, a relay, a light switch, an accelerator sensor, and a light. And, the present invention maintains a visual field of a driver and prevents dissipation of electric power by turning off a light automatically in a case of stop of a vehicle. With the growing need to conserve energy, more people are becoming conscious of energy consumption and are looking for ways to reduce costly waste associated with electricity. Though most consumers do not think about lighting until the light bulb fails or the power goes out, expenses incurred due to lighting have been found to be a large part of overall energy consumption and lighting has now become the focus of efforts aimed at reducing the high cost of electricity. The purpose of our project is to design an Automatic Light Control Device (ALCD) to help curb the high cost of internal lighting while creating a convenient effortlessly lighted environment for the consumer. Motion detectors cause lights to turn on after entering the room and off after no movement is detected for a certain amount of time. This unit is efficient; however, energy is loss due to the presence and absence of movement in a particular room by the sensor continuously activating on or off. Unneeded cycling uses more power and defeats the intended purpose of saving energy. The ALCD will save energy by eliminating false conditions, thereby minimizing light cycles.
