An automatic light signaling bicycle communication system includes a wireless relay module, a light module, and an external master device. The wireless relay module includes a relay processing unit and a relay communication unit. The relay processing unit controls the relay communication unit to wirelessly communicate with the external master device according to a simplified network protocol. When the relay processing unit receives a brake command through the relay communication unit according to the simplified network layer protocol file, the relay processing unit generates a relay brake command and broadcasts the relay brake command to a light communication unit of the light module according to MAC protocol, allowing a light processing unit of the light module to light up a brake light automatically. The light module only requires a low cost RF receiver chip for receiving broadcasted commands, rather than requiring an expensive chip for handling network communications.
