I need a strobe controller for a model im building. Needs to flash 4 strobe lights like Amtrak and NJ Transit. There was one person who made a fantastic kit but no longer makes them, aaron heine electronics. He made those rotary beacon kits too.
You might want to look at the NCE "Light It" decoders if you use DCC. They are about the size of a postage stamp and have 3 selectable outputs. including strobes. If you need more outputs you can daisy chain them together for more.
