A multi-directional signal assembly includes a signal display assembly 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 assembly is mounted to the signal display assembly to maintain the signal display assembly in a substantially upright, operative orientation when deployed. An illumination assembly comprising one or more illumination members is mounted to the signal display assembly, and is actuated to increase visibility of the signal display assembly while it is deployed on the surface of a body of water.
