An LED light signal, in particular an LED railway light signal, contains a signal generator for generating varicolored light spots. The LEDs are embodied as multicolor LEDs, in particular RGB LEDs-Red/Yellow/Blue LEDs. In order to be able to utilize the possibilities for color mixing and thus for realizing a large number of color variants for safety-relevant signaling technology, the signal generator has at least one optical sensor for monitoring a color locus and a light intensity reliably in terms of signaling technology.
