Abstract: An orientation-adjusting device for a vehicle head light comprises a housing encasement, an active unit, a driven unit, a cover, and driven screw rod, an elastic unit, and an elastic sealing unit. The housing encasement is installed with an elliptical hole and an axial hole. The active unit has an axial portion axially installed to the axial hole, and a gear portion located in the housing encasement. The driven unit is installed with a gear portion engaged with the gear portion of the action unit, and an axially-formed penetrating hole, which includes a threaded hole section near the active unit and a threadless hole section remotely away from the active unit. The cover is installed on the housing encasement to cover the interior of the housing encasement for preventing the driven unit from projecting out from the housing encasement.

Abstract: A direction turning device for headlights of an automobile comprises two operation mechanisms, namely, direct operation mechanism and electromagnetic operation mechanisms. For the direct operation mechanism, if an automobile with lefthand drive, the device is connected to the left headlight; if an automobile with righthand drive, the device is connected to the right headlight. Where, the electromagnetic operation mechanism is connected to both left and right headlights and activated synchronously with the steering system. This disclosure has been characterized in the simplized structure and the longevity of use because the electromagnetic mechanism is turned off during daytime driving.

Abstract: A steerable and height adjustable light pod comprising a multi-directional light emitting means is mounted atop a vehicle guide wheel for synchronous angular movement therewith.

Abstract: A motor vehicle comprises a pivotal support member having at least one headlamp secured thereto, an unidirectional motor which rotates its output shaft in one rotational direction only when energized, cam and linkage means whereby rotation of the output shaft of the motor is converted into a pivotal movement of the support member about its pivot axis to adjust the headlight angles. Also provided is an electric circuit for energizing the motor which comprises a first group of electrical contacts which are connected in series with a second group of electrical contacts, respectively, a contact disc in slidable engagement with the second group of electrical contacts, and a manually operable means for selectively connecting one of the first group of electrical contacts to a battery. The contact disc is electrically connected in series with the motor and also mechanically connected to the output shaft of the motor to be rotated thereby.
