Zusammenfassung:	Problem to be Solved: To provide a lighting device that is capable of easily securing the required brightness throughout the vehicle in an emergency with a simple and convenient configuration, and is capable of further improving the safety at the time of evacuation with no need for increasing the cost. The lighting device includes an indoor lamp (11), being provided in the cabin of a railroad vehicle (1) in order to wholly irradiate the inside of the cabin over the longitudinal direction of the vehicle, a vehicle body power supply (20), supplying electric power to the indoor lamp (11), and a storage battery (30), being charged with a voltage applied by the vehicle body power supply (20). The indoor lamp (11) includes a general lamp light source (12) and a standby lamp light source (13), being lighted at an illuminance lower than that at which the general lamp light source (12) is lighted, and the general lamp source (12) being supplied with electric power from the vehicle body power supply (20) not through the storage battery (30), while the standby lamp light source (13) being supplied with electric power from the vehicle body power supply (20) through the storage battery (30). In an emergency, electric power is supplied from the storage battery (30) only to the standby lamp light source (13), and the standby lamp light source (13) is continued to be lighted at the low illuminance.
