Here is a Model Power #700 "HO" Scale "THE OUTLAW" that lights up.
This is a road scene Train Billboard that goes on the side of your highway on your train layout.
2 wires hook up to your A.C. Terminal on your power supply and is compatable with 12-19 Volts. It'll even work on a 9 volt battery, tho' not quite at full brightness. It is 3 1/4" Long, the screen part is 1 & 1/4" high and it is 2" high including the base which forms a little shelf.
Billboard would look great dressing up your road highway on your layout.
