Overview
The Werma 641 400 00 is a clear continuous light element designed for modular signal tower applications. This filament-based light module operates across a broad voltage range (12-240V AC/DC) and provides reliable visual indication in industrial automation, manufacturing, and process control environments. With IP65 ingress protection and a standard 70mm diameter form factor, it integrates seamlessly into existing KombiSIGN 71 signal tower systems.
