Abstract: A plurality of lamps 21 to 28 inclusive are supplied with a voltage one after another in sequence. A time duration during which the voltage is supplied to each of the lamps 21 to 28 inclusive is controlled in PWM fashion to restrict an amount of voltage supplied thereto. A current detect circuit portion 36 solely detects all of the voltages supplied to the lamps 21 to 28 inclusive, respectively. Each of the voltages exceeds a threshold value, a dead band between two adjacent voltage supply durations. Thus, it is possible to restrict possible electromagnetic noises which are generated upon voltage supply to lamps 21 to 28 inclusive in a vehicular lamp control apparatus in which the lamps 21 to 28 inclusive are supplied with voltage from a high voltage battery 11.

Abstract: A system for improving vehicle safety and reducing driver stress by signalling drivers of oncoming vehicles and vehicles behind a vehicle to dim or turn on their vehicle's headlights. The signalling system comprises a front signalling light, a rear signalling light and a control system. The signalling lights are focused and aimed in the direction of drivers of oncoming vehicles and vehicles behind a vehicle to gain their attention without disturbing other drivers. A series of flashing light beams are transmitted in a controlled manner to distinguish the lights from other vehicle and traffic lights. The signalling system is activated by a switch which is located adjacent to a driver's hand to reduce the time for activating the system. The system has two operating states, one state where the signalling lights are timed to flash "on" and "off" for a predetermined amount of time and another state where the signalling lights flash continuously "on" and "off". Several embodiments are disclosed to illustrate the broad scope of the invention.

Abstract: A sequential control circuit capable of sequencing through a number of stable states in a predetermined order, starting from a predetermined stable state and sequencing in either of two opposite directions. A contact maker having two transient positions is connected to a timing circuit and to a logic circuit. In response to assumption by the contact maker of one of its transient positions, the timing circuit provides a timer signal delayed with respect to the interval of that transient position. The logic circuit sequences through a number of output conditions corresponding with the stable states in a direction determined by the particular transient position. The logic circuit includes circuitry for placing the circuit in a predetermined one of the output conditions upon initial start up.

Abstract: Apparatus for controlling the energization of vehicle headlamps and parking lamps in response to the settings of a light switch, an ignition switch, and a door responsive switch. In a first embodiment the parking lights are energized when the light switch is momentarily closed and deenergized when it is held closed for a predetermined time. The headlamps are similarly energized and deenergized when the ignition switch is in a vehicle operative setting. Momentary closure of the light switch while the headlamps are energized alternately energizes bright and low beam headlamps. The parking lamps and headlamps are automatically extinguished when the vehicle door is opened after the ignition switch is placed in a vehicle inoperative setting. In a second embodiment additional time delay circuitry is provided for maintaining the vehicle lamps energized for a predetermined time after the operator has left the vehicle.
