The invention discloses an indicator lamp module for rail traffic and a rail traffic safety prompt system, and relates to the technical field of rail traffic. The indicator lamp module comprises a first microprocessor module, a first red lamp indication module, a first green lamp indication module, a first image acquisition module, a multi-degree-of-freedom adjustment module, a first communicationmodule, a first power supply module and a standby power supply module. The indicator lamp module receives a control command through a wired network or a wireless network, and controls the first red lamp indication module and the first green lamp indication module for indication according to the control command issued by a track traffic transportation system; and the indicator lamp module is usedfor indicating a starting or stopping command so that the instability of transmitting signals through flags or interphones can be effectively avoided, a driver can accurately and timely obtain the starting and stopping signals of a train, and the running safety of the train is improved.
