Inspired by development and end usage of the BROS axle counter system, IMP-Telecommunications has developed LED Signal LL-136 – an LED light source intended for use in railway color light signals. It was developed as a replacement for two-filament light bulbs in legacy, relay-based interlocking systems, as well as a light source for signals in modern, electronic-based interlocking systems. First signals are installed in railway station Pančevo bridge.

Serial production has already started and first mass installations are expected for the railway station Ovča in October.
