A portable distress light signal device generates a visual S.O.S. distress signal indication visible from a significant distance away. Indicia including the letters “SOS” are disposed on either side of the device. A first set of light emitting diodes (LEDs) are disposed on both sides of the unit, each positioned within the interior of the region defined by each letter of the “SOS” indicia. A second set of LEDs, preferably of substantial power and luminosity, is likewise disposed on both sides of the unit, within the interior of the “O” portion of the “SOS” indicia. A power cord and power plug couples the unit to a source of electrical power, such as the cigarette lighter socket or 12-Volt accessory socket of an automobile or other vehicle. Powerful permanent magnets are preferably disposed about at least the bottom and right side edges of the housing, permitting the driver of an automobile to rapidly secure the unit to a ferromagnetic surface of the vehicle, such as the driver-side door or roof, in both cases with the SOS indicia oriented in horizontal orientation for easy recognition by passersby. Hazard warning stripes are disposed about the front and back sides of the housing for further enhanced visibility. Upon the application of power to the unit, an internal microcontroller repeatedly switches power to both the first and second sets of LEDs on and off causing them to pulse in a repeated sequence that corresponds to the S.O.S. signal in international Morse code.
