A multi-directional signal assembly includes a signal display unit having one or more display surfaces, and at least one signal indicia affixed to each display surface. The multi-directional display assembly comprises a buoyant construction such that the signal indicia affixed to the display surface(s) are readily visible above the surface of a body of water in which the assembly is deployed. A counterweight mechanism is mounted to the signal display unit to maintain the signal display unit in a substantially upright, operative orientation when deployed. An illumination system comprising one or more illumination members is mounted to the signal display unit, and is actuated to increase visibility of the signal display unit while it is deployed n the surface of a body of water.
