A traffic signal lamp includes a plurality of light-emitting devices. Each light-emitting device includes a light-emitting element, a power distribution module, a power module, a controller and a measuring element. The power module is configured for converting an alternating current (AC) into a direct current (DC) and supplying the DC to the light-emitting element and the power distribution module. The measuring element is electrically coupled to the power distribution module and the light-emitting element. The controller is electrically coupled to the power distribution module and the measuring element. When a selected-one of the light-emitting devices receives the AC, the power distribution modules of the selected-one provides the DC to the controller and the measuring element of the selected-one and the power distribution module of the others of the light-emitting devices.
