摘要:
A vehicle lighting system, for use in automobiles or trucks has a tail lamp relay, connected so electrical current flows through the vehicle battery, a tail lamp, and the tail lamp relay when the relay is on; a tail lamp switch; a battery low voltage sensor; taillamp programming means; and means for sensing that the vehicle is in operation. The system also has control circuitry that turns on the relay in the first state when the vehicle is in operation and the tail lamp switch is on, or following the vehicle ceasing operation, the taillamp programming means is on, and the battery low voltage sensing means senses a high battery voltage, but where the relay is turned off when the vehicle is not in operation and either the taillamp programming means is off, the taillamp switch is off, or the battery low voltage sensing means senses a low battery voltage.

The apparatus for automatically adjusting a direction of a light axis of a vehicle headlight includes a steering angle sensor, a vehicle speed sensor, a memory for storing a plurality of control maps each of which defining a relationship between the steering angle and a swiveling angle, a processing unit for performing a map switchover by which one of the plurality of the control maps is selected depending on the vehicle speed and the steering angle, and an actuator for swiveling, from an initial direction, the light axis of the vehicle headlight by the swiveling angle defined by one of the plurality of control maps selected by the processing unit. The processing unit performs the map switchover when the steering angle is changed to outside a predetermined angular range around a neutral angular position of the steering wheel.
