Designed as an LED (12), a first lighting device radiates light with a first light intensity (FLI) in a first main radiating direction (FMRD) (18). Also designed as LEDs (20,28), a second lighting device (SLD) radiates light in a second main radiating direction (SMRD) (14). A second light intensity is less than the FLI. The SMRD is different from the FMRD. The SLD creates a section of an evenly illuminated signaling disk (30). |
