  • LEDs Light signals or LEDs on the basis of LEDs - light emitting diodes - instead of incandescent lamps are increasingly being used in many areas, especially in railway signaling. LEDs are comparatively inexpensive, durable and bright. The trend is towards HLED - high current LED - whose light intensity is so high that even a single HLED emits enough light per light point to achieve the required brightness.
