Abstract
A rail vehicle emergency lighting system for a rail vehicle includes a main lighting system with light emitting diodes. When a main lighting power supply is active, the light emitting diodes of the main lighting system are lit with a main lighting intensity. When the main lighting power supply fails, the light emitting diodes of the main lighting system are lit with an emergency lighting intensity. The emergency lighting intensity is reduced compared to the main lighting intensity.
