Abstract
PURPOSE: To prevent the forgetting of turning on/off operation of a headlight, by automatically turning on or off the headlight depending on the speed of a vehicle.
CONSTITUTION: A signal proportional to the speed of a vehicle is always supplied from a speedometer 1 to a controller 2, which acts to turn off the headlight in accordance with the signal below a speed regarded as safe for the running of vehicle and to turn on the headlight in accordance with the signal above the speed. The controller 2 can be connected or disconnected by a normally installed headlight switch. Whenever the driver wants to keep the headlight turned on, he can operate the headlight switch to keep the headlight turned on. Therefore, the driver can select the use or nonuse of the controller 2.
