Systematic warning: The HELLA OWS7 optical warning system impresses with its sophisticated, modular design. This warning system can be configured flexibly, which means numerous applications can be covered – from the basic to the high-end variant. In addition to the main beacons, the modular system also includes alley lights, work lamps, hazard warning lamps, and a signal bar with running lights. There are also panels in different color variants as well as the amber or transparent domes. The dome color depends on the light module used.

In the 12V example configuration 2RL 010 710-991, the OWS7 warning system consists of a 360° LED module with strobe function and high-power LEDs arranged in a semicircle. The system is complemented by alley lights and a 5-module LED signal bar (LSB) with running lights and amber domes.

The OWS7 system has a flat, compact, and aerodynamically optimized design. The LED technology used is energy-efficient and durable, and ensures a high warning effect through high light values. The material used is extremely robust and resistant.
