Looks like an economical solution - $9 each including shipping for one, $15 for two.
A couple of observations / questions from someone who isn't an electronics guru:
1) Input says 3-12v DC. If the crossing signal is initiated by an insulated track section (sends AC from the track), is it correct to assume that a relay and DC power source are also needed to provide the appropriate input voltage?
2) Output is 3-12v DC to power LEDs. If the signal has incandescent bulbs, what else needs to be added between the output terminals and the bulbs?
