A floor sign device for use on wet, newly waxed, and painted floors to warn and caution pedestrians travelling on the floor of the surface conditions. The device includes first and second panels pivotally coupled together along their top edges. An elongate light tower extends from the top edges of the panels with a light source mounted to the upper end of the light tower. A sound recording and playing device is provided in the light tower. The sound recording and playing device has a microphone and a speaker on the light tower. A motion detecting sensor for detecting motion from a nearby pedestrian is also provided on the light tower. The motion detecting sensor is electrically connected to light source and the sound recording and playing device. The light source is activated to illuminate and the sound recording and playing device is activated to project an audible prerecorded warning when the motion detecting sensor detects motion from a nearby pedestrian.
