A 189 Siemens type C940ES traffic controller, part of a shipment to the Glückstein district of Mannheim, was also the 25,000th traffic controller of the series.

The controllers will be used to upgrade traffic signal control at all junctions in Glückstein, and is specifically designed to meet the requirements for controlling 40-volt LED (light-emitting diode) lighting equipment, which saves up to 90 per cent of the energy consumed by conventional bulbs.

The high safety level of the controllers installed in Mannheim will check changes in the behaviour of the LED signals at the extremely rapid rate of 1,000 times per second, and report any conflicting signal states and defective lamps.
