to clarify, the semaphore I have is the NJ International 2 light
#525-1010. It actually has 4 very very thin wires, along with the 2
wires for the light. 2 light? One light? I am only going from the
description found in online listings. Perhaps what is meant by 2 light
is 2 position with a single light bulb? Not sure. Anyone want to
correct my thinking, have at it:)....thanks--tyler
