An apparatus and system for incorporating a resilient source of high-visibility illumination into an article of footwear. A biomechanically-sound and hermetically-sealed electronics module contains a microprocessor, power source, and at least one light source, such as a light emitting diode, or LED. The LEDs are not externally visible, but rather illuminate a diffusive substrate that is incorporated into the construction of the footwear, allowing for visibility from substantially every angle above the bottom of the sole. A control panel enables the wearer to turn the power on and off, change colors, rotate through transition effects, and the like. A charging pad allows for the wireless and contact-less recharging of the onboard power source.
