One of the main features of the new VarioSIGN is the electronic modularity of the individual signal stages which replaces the mechanical modularity in traditional signal towers. Depending on the product type, a stage-by-stage or complete, attention grabbing illumination of the signal tower is possible. The lighting configuration is visible from one or both sides as required. The new VarioSIGN LED signal tower is also available with an optional loud, integrated buzzer. This combination generates a sound output of more than 85 dB, ensuring a maximum attention-grabbing effect.
