Abstract

A lighting system for a train unit, the lighting system comprising a light source, a light level detector and a controller, the controller being configured to change the output of the light source for a period to a predetermined level, to receive from the light level detector a measure of the ambient light level and to adjust the illumination provided by the light source dependent on the measure of the ambient light level towards a target power level.
