This is a really nice tower light. It is easy to attach with mounting holes, and you can rotate the light mount so it can be horizontal, vertical or any angle in between (180 rotation).
This is the one color version: Red
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 the LED light or buzzer. The red wire controls the red LED light and the orange wire is what controls the buzzer which will sound continuously when the wire is grounded.
