Abstract

A remote control assembly comprising a signal light and a spotlight comprises a lamp receptacle, a combined light, two driving device for the combined light, a base stand, circuit board and suction disk. The combined light includes signal light and spotlight, lamp shields, reflector and supporting shafts. When assembled, it is rotatably mounted in the lamp receptacle. One of driving device can make the combined light rotate upward and downward in the range of 250°, and can provide large visual angle in the evening or at night, even beyond 90°, and the other driving device can make the combined light rotate horizontally in the wide range of 360°. In addition, it (the combined light) has good performance of weather proof and super bright illumination. In emergency condition, its flashing light can be seen from several kilometers away. It is suitable for use on deck, galley, trailers and utility vehicles.
