The signal device includes a housing containing a light and having a front face adapted to receive, in removably mounted engagement thereon, a first message screen selected from a group of message screens. Each message screen of the group of message screens is preferably a substantially planar sheet permitting the passage of light therethrough when mounted in the front face and backlit by the light. The first message screen has a first distress message formed thereon which is illuminated when the message screen is backlit by the light. Each message screen of the group of message screens has a different distress message for communication by the backlighting by the light so that a user may select an appropriate distress message by selecting the corresponding message screen for mounting onto the front face. The light is activated by a switch mounted to the housing and cooperating with a power supply.
