Abstract
In certain exemplary embodiments, an apparatus for rotating one or more vehicle lamps can include a case body, a motor, a printed circuit board, and/or a gear reducing mechanism. The motor can be mounted on the outside of the case body and/or can include a case shell and/or an end cover. The revolving shaft of the motor can be supported on the case shell and/or the end cover of the motor by a first bearing and/or a second bearing respectively. The end of the revolving shaft of the motor can enter into the case body and/or be fixed with a driving gear which can engage with the gear reducing mechanism. The output shaft of the gear reducing mechanism can actuate the vehicle lamp, so as to change the direction of irradiation of the vehicle lamp.
