Overview
The WERMA 840 300 00 permanent light element is a solid-state continuous illumination module designed for the KombiSIGN 70 modular signal tower family. This component integrates a B15d socket to accommodate the light source and indicates a certain condition to the operator through steady-state lighting. Manufactured in Germany by WERMA Signaltechnik, this module is built for reliability in machine automation, traffic control, and industrial safety applications.
