PURPOSE: An automatic emergency flasher for a sudden braking of a vehicle is provided to simplify components by determining sudden deceleration with an amount of currents generated in a generation coil. CONSTITUTION: An electromagnetic coil(C1) is combined with the outside of the side of a body(H1). A generation coil(C2) is combined with the outside of the body and generates a current. A neodium magnet(M1) is inserted into the front of a moving weight casing(H2) and moves a moving weight. A ferrite magnet(M2) is inserted into the rear of the moving weight casing and generates a current. An emergency lamp is automatically on and off in a sudden braking.
