A clothing pin emitting light of the present invention comprises a head unit including a fixing member with a grounding unit and a hanging member with a hanging groove on both sides respectively, and including an LED lamp; and a spring having a first supporting unit on one side where a first current carrying unit coupled with the fixing member by bending the center to generate torsion elasticity, and having a second supporting unit on the other side where a second current carrying unit selectively coupled or separated from the hanging member. When the grounding unit and the first current carrying unit is mutually grounded by sliding motion while the second supporting unit is coupled with the hanging groove, the current of a battery installed on the bent center of the spring applies a current to the LED lamp to emit light.
