Abstract

The method involves displaying a predetermined permissible signal term by a definite LED-illuminant in an operating condition. A subset of the LED-illuminant is activated within a defined time internal during the operating condition. The subset of the LED-illuminant activated during the operating condition represents a non-permissible signal term. A command is triggered by wireless communication or by a position of a vehicle. An independent claim is also included for a utilization of a method for testing a signal based on an LED-illuminant.
