Alert tower lights are really easy to use. The brown wire is the common +12V power line, then the other wires are connected to ground to activate each of the three LED lights: red wire for red light, yellow wire for yellow light and, you guessed it, green wire for green light. The final orange wire is what controls the buzzer which will sound continuously when the wire is grounded. We did notice that you can't have both the yellow and red lamps on at once, and in general its best to only have one lamp lit at a time for max brightness. The buzzer can be turned on whenever, it does not seem to be affected by the lights.
