    I am completely at a loss for the meaning of "the tower light".

    However, if your question is about using a relay with a 12 volt coil to switch a different voltage, then yes, it's done all the time.

    The tower light is the LED light (with different color of red, orang, green) that used in industry for the station testing status. I need to use the relay to light out the different color of the tower light when the different status occur for the station (e.g red color led on when status fail).

    Do we get to see a schematic or anything?

    I really hate guessing at these kinds of things. Guessing leads to smoke, and expense.
