PURPOSE: A detection device with a tail lamp is provided to easily recognize alarm sound for a driver and a pedestrian by installing a resonator in an alarm generator. CONSTITUTION: A housing includes a base(12) and a cover(14). An internal space is formed between the base and the cover. A light emitting diode(40) is radiated as soon as a vehicle moves back. An action detection sensor(50) is installed in the internal space of the housing. The action detection sensor senses the object in the back of a vehicle. An emergency signal unit comprises an alarm generator and a resonator. A control unit(70) controls the operation of the emergency signal unit.
