A flasher relay for driving a left turn signal lamp and a right turn signal lamp of a vehicle to flash includes a main body and a control circuit. The main body includes a base, a casing, and a circuit board. The circuit board is disposed on the base. The casing is mounted on the base and covers the circuit board. The control circuit is disposed on the circuit board. The control circuit includes a microchip having an input terminal coupled to a field-effect transistor and an electromagnetic buzzer. A drain of the field-effect transistor and one end of the electromagnetic buzzer are coupled to a node B. A heat dissipation terminal of the field-effect transistor is coupled to the node B, and the node B guides thermal energy to a wire.
