Abstract
An apparatus for a model toy train includes a circuit configured to supply an output signal to energize at least one stationary light to simulate a light having movement like a mars unit light display.
Claims21
An apparatus for a model train operating on a model track to simulate movement of an oscillating light unit, comprising:
- a lamp display having at least one stationary light;
- a circuitry configured to energize the at least one stationary light and having a processor that comprises:
- an input for receiving a first signal;
- and
- an output for supplying a processor output signal that is indicative of the first signal;
- and
- at least one lamp controller that is in electrical communication with the processor and the lamp display, and receives the processor output signal and converts the processor output signal into a controller output signal to energize the at least one stationary light intermittently to simulate the movement of the oscillating light unit without requiring actual movement of the lamp display.
