New SingleLiT Single Light Illuminates the Darkness.

With the development of the new single light for tunnel safety, the Rhomberg Sersa Rail Group's LED emergency light product family has gained a new member.


The SingleLiT serves as a perfect complement to the already known RSRG handrail, handraiLIT, responsible for lighting the tunnel escape route in emergencies. It is optimally suited for safety lighting systems according to EN50172 or the TSI-SRT (Technical Specification for Interoperability).


The lighting innovation was developed based on the requirements of DB Netz AG. It strictly adheres to the sustainability principles of the RSRG which means only long-lasting materials are used. The power consumption has been optimised and is only around 4W. Moreover, the light can be easily repaired if necessary. At the end of its lifespan, it will be disposed of in an environmentally friendly manner.


The SingleLiT stands out thanks to its innovative light guidance system based on LED lenses and the corresponding light exit surfaces of the light head. The light is perfectly directed onto the escape route in the tunnel, thus ensuring illumination up to 10 metres in both directions. The light head is adjustable between 90 and 180°, thereby adapting to any tunnel wall courses or profiles
