Показать описание
Signal switches to danger as the train passes over the infra-red sensor adjacent to the signal. It then automatically returns to green, via yellow and double yellow.

Model ASP1A is for common-cathode led signals and ASP2A is for common-anode signals. Both feature optional led fading to simulate filament bulbs.
