ABSTRACT:
Disclosed herein is a multi-functional traffic signal stick, which has a red signal LED part for providing a signal stick function and a white signal LED part for providing a flash light function, and which a police officer carries on the road. The multi-functional traffic signal stick can be carried conveniently as a flash light by telescoping each joint of a length-adjustable flashing tube manufactured in an antenna type into a larger tube, and used as a signal stick, which is well seen from a far distance, by stretching each joint of the length-adjustable flashing tube like an antenna. In addition, the present invention can serve to inform danger or accidents when being mounted uprightly on the road or a proper place such that three supporting rods mounted on a grip part at regular intervals are unfolded to support the signal stick.
