An impact-activated illuminating leg wrap is configured to provide light on a moving animal. The impact-activated illuminating leg wrap includes a first layer joined to a second layer wherein the second layer further comprises a hook fastener. An upper strap is fixed to the loop fastener and attached to an upper strap loop fastener. The upper strap is adapted to be wrapped around a leg of an animal forming a rear leg wrap concave contour. An upper reflective strap is attached to the hook fastener and perforated with a series of upper reflective strap perforations. A series of upper reflective strap light emitting diodes is inserted through the series of upper reflective strap perforations and connected to the upper reflective strap. A first microcontroller is attached to the second layer with a first elastic strap.
