Abstract
In order to visually indicate the readiness of a vehicle alarm system or the locked condition of a vehicle door, an electro-optical indicating element is inserted into the locking button of a vehicle locking system. The light-emitting diode, during the pulse operation, is operated with a no-pulse period which is relatively long in comparison to the flashing pulse.
