The present invention discloses a signal light, including a lighting circuit and a light-emitting mechanism. The light-emitting mechanism includes a plurality of groups of light-emitting diode (LED) light panels connected in parallel. The lighting circuit includes an alternating-current side main circuit, a direct-current side main circuit, and a control unit. In addition, the present invention provides a signal light system, including the signal light, a lighting control circuit, and a power supply. The present invention may implement, by improving a circuit topology, safety cut-off of a light-end main circuit to turn off the light. The present invention detects, by improvement, a voltage and a current of each string of light beads on the LED light panels, so that an operation status of each string of light beads can be reflected. When the light beads are damaged by 30% and 50%, communication is performed by a main power supply circuit through a carrier wave (without adding a new connecting wire), and status information of the LED light panels is sent to the lighting control circuit.
