Abstract: A safety device for signaling various firing conditions for vehicles armed with guns includes an internal housing electrically connected to an external housing. Both the internal housing and the external housing have bulbs of various colors or lenses of various colors with bulbs behind the lenses. Various colors or combinations of colors are used to signal various firing conditions for the safety of personnel near a gun equipped military vehicle. The colors on the internal housing correspond to the colors on the external housing. Switches are located on the internal housing so that military personnel can produce a desired signal from the inside the gun equipped military vehicle. Each switch enables or turns "on" a light on the internal housing and the corresponding light on the external housing. This safety signaling device is most useful when military personnel have to perform exercises during the night hours.
