A portable distress light including a plurality of light emitting diodes and a light mode switch to power the diodes so as to provide a flashing white light, a flashing infrared light, a flashing blue light and a steady white light. Status indicators are included on the device to correspondingly identify the operative mode selected. The light emitting diodes include top-emitting diodes and side-emitting diodes that are arranged on a printed circuit board in a variety of configurations to provide an optimum light pattern. Exemplary configurations include positioning the light emitting diodes into a triangular pattern, and a square or rectangular pattern. The distress device further includes a variety of reflectors that are disposed over the light emitting diodes to provide a horizontally dispersed light pattern. An operating circuit provides the benefit of a delay period between mode selections. An alternative embodiment provides a distress light including a cylindrically-shaped form having a top dome attached to a cylindrical body.
