Get this great MARS light simulator for your Model Train, we have designed it based on what the real trains do.

We have this circuit ready to run on your power supply. Choose the 7-19V AC/DC/DCC option for your train transformer or your non regulated wall adapter.

Choose the 5-12 volt DC option if you want to run this Mars light on a 9 volt battery or other battery supply

Choose the 3 volt version for 3 volt battery or our 3 volt regulated adapter.

The Mars light comes with our soft Warm White LED. If you want the shade just a little bit more yellowed, you can add a very thinned coat of yellow paint to shift the color even older era. We don't recommend our Yellow LED on this circuit because our yellow is a strong saturated shade of yellow.

The circuit has 8" input to the circuit and 8" output to the LED. You can shorten either of these wires if needed.

The circuit is loaded with a 3mm warm white LED. We can add a different LED, of another size or color. Contact us for options.
