A safety illumination device that is mountable to an edge of a ski or snowboard is provided. The device has a curved exterior housing with a front window panel along the convex front portion, an upper window panel along the top and a concave cutout along the rear portion. A circuit board containing control circuitry, a power source and two arrays of lights is housed within the exterior housing. When the device is turned on, light is emitted through the window panels. This assists persons uphill and downhill from the user to see the user in the dark. Selection of an illumination pattern is controlled by a magnetic wand that the user waves over the upper surface of the device. Users may thus easily operate the device and customize their lighting experience. The device is secured to a ski or snowboard via the concave cutout and a pair of screws.
