Abstract: A rotatable vehicular lamp assembly includes a main frame having spaced-apart top and bottom main plates, a lighting unit, and a drive unit. The lighting unit includes a lamp seat holder connected pivotally to the top and bottom main plates for rotation relative to the main frame, and a lamp seat connected to and rotatable synchronously with the lamp seat holder. The drive unit includes a motor mounted on the main frame to rotate the lamp seat holder relative to the main frame. A vibration-limiting element is disposed between the main frame and the lamp seat holder to limit vibration of the lamp seat holder.

Abstract: A vehicular rotatable lamp assembly includes a main frame, a lighting unit including a rotatable lamp seat holder connected pivotally to the main frame and having a gear-toothed plate, and a drive mechanism including a motor mounted on the main frame for rotating the lamp seat holder to a predetermined angle, a motor gear connected to the motor, and a correction gear meshed between the motor gear and the gear-toothed plate. An angle correction mechanism includes an angle indicator rotating along with the correction gear for indicating a rotating angle of the correction gear, and an angle sensor for detecting the rotating angle of the correction gear. A control unit controls the motor to correct an angular position of the lamp seat holder when the rotating angle detected by the angle sensor is not consistent with the predetermined angle.

Abstract: A rotatable vehicular lamp assembly includes a main frame, and a lighting unit including a lamp seat holder connected pivotally to the main frame, and a lamp seat connected to and rotating synchronously with the lamp seat holder. A drive unit is mounted on the main frame to rotate the lamp seat holder relative to the main frame. A limiting unit is provided to limit a rotating angle of the lamp seat holder to a preset angle, and includes at least one light sensor on the main frame, and at least one light obstructing piece connected to and rotating synchronously with the lamp seat holder. The light sensor sends a signal to the drive unit to stop rotation of the lamp seat holder when detecting an arrival of the light obstructing piece.

Abstract: A vehicular rotatable lamp unit includes a main seat adapted to be mounted on a vehicle, a lamp seat assembly connected pivotally to the main seat, a conducting wire, a first contact assembly mounted on the main seat, and a second contact assembly adapted to be connected to a power source of the vehicle. The conducting wire has a first end connected electrically to the lamp seat assembly, and a second end opposite to the first end. The first contact assembly includes a first contact member connected electrically to the second end of the conducting wire and rotatable along with the lamp seat assembly. The second contact assembly includes a second contact member to contact the first contact member.

Abstract: A direction adjustable device includes a motor drive unit for driving a turnable unit to turn, and a sensor assembly which includes a force transmitting member, a cable having first and second ends connected to the force transmitting member and a steering linkage, respectively, a rotary control switch coupled to the force transmitting member such that pivoting movement of the latter is transmitted to a signal processing unit, and a reversing member adapted to be connected to the steering linkage.
