LED technology railway signals

The 1st generation LED units (available since 2001) and the LED Signals EU (available since 2006) are officially approved for use in Austria, Slovakia and Germany. They use high intensity LEDs.

The excellent visibility of the LED Signal EU is the result of a combination of high power LED as a central light source and a special lens system.

In combination with the highest safety class level SIL 4, Zelisko LED technology meets the highest demands of modern railway systems.

In the meantime more than 35.000 pcs are currently in operation or being tested by the ÖBB or private operators in Austria, as well as by many other international railway companies. The LED Signal EU meets the requirements for the Deutsche Bahn LED and has been formally approved by the EBA as well as by the Slovakian Railway.
