Abstract: The invention relates to a light management device for a vehicle, in particular a railway vehicle, the vehicle comprising at least one car. The device comprises:



at least one light source, the at least one light source emitting light radiation with at least one optical characteristic,
at least one sensor selected from a sensor for measuring a passenger density aboard the vehicle, such as an axle load sensor, a vehicle position sensor, and/or a clock,
a control unit connected to the at least one sensor, and to the at least one light source, the control unit being configured to control the at least one optical characteristic of the light radiation based on a measurement of the at least one sensor.
