The Werma 644.130.75 is a red LED flashing light element featuring patented TwinFLASH technology, part of the KombiSIGN 71 modular signal tower series. Designed for high-attention visual signaling, TwinFLASH mode alternates between double-pulse flashes to increase detection in noisy or busy industrial environments. The unit operates at 24 V AC/DC and uses long-life, energy-efficient LEDs. Its Ø70 mm impact-resistant polycarbonate dome provides high optical clarity, and the IP65 rating ensures it performs reliably in dusty, wet, or vibration-prone locations. The tool-free twist-lock base allows easy integration into stackable towers for machine status indication, hazard alerts, or process warnings.
