A light-out detection device includes a mounting structure with a sensor for measuring a light output, wherein the mounting structure is configured as retrofittable structure to mount at a front side of a signal, a processor board with an actuator, the processor board being operably coupled to the at least one sensor, wherein the processor board is configured to control the actuator such that the actuator switches from a first state to a second state when the measured light output is less than a predefined threshold.

A housing, an LED system, and an alignment module supported in the housing to mount the LED system in an interior space in the housing, dampen vibration(s) of the LED system in the interior space, and automatically align a focal point of the LED system. Such a lightening system may be applicable for a traffic/rail signal.

The invention relates to a sub-assembly for a searchlight signal comprising three distinct light emitting diodes and an interface module for connecting the three diodes to a controller. The interface module comprises: a light input adapted to receive a signal for feeding a light emitting diode, a first relay having an active position and an inactive position, and a second relay having an active position and an inactive position, such that: when the second relay and the first relay are in the inactive position, the light input is fed to a first LED, when the first relay is in the active position, the light input is fed to a second LED, and when the second relay is in the active position, the light input is fed to a third LED.

A rail lighting fixture for providing illumination along a rail of a railway track includes a housing arranged for attachment to the rail and provided with at least one aperture. At least one light source is provided in the housing and arranged to emit a light beam. The lighting fixture is arranged to direct the light beam through the aperture towards a lighting direction, and the lighting direction has a component that is parallel to a longitudinal direction of the rail.
