We installed a General Railway SA-1 Searchlight this week at my friend's home in Southern Illinois. Top head has Red/ Green/ Yellow specticals, and the bottom head has Red/ Yellow/ Lunar. This combined with some cheap automotive flashing relays, offer us several different signal indications we can display.
