High-intensity LEDs are mountd on or form part of an object to be illuminated. The object has first electrical terminals thereon that are coupled to the LEDs. A portable electrical circuit having second terminals for detachable coupling to the first terminals on the object causes the LED to flash and provide visibility to the object. The electrical circuit is contained in a package that has a first Velcro strip thereon. A second Velcro strip is mounted on the object near the first terminals so that the electrical circuit can be attached thereto by the Velcro strips and the electrical terminals coupled together.
at least one miniaturized light-emitting diode embedded in the body of the shoe;
first electrical contacts externally mounted on said shoe and coupled to said LED; and
a portable kit having a complete electrical control circuit contained therein for removable coupling to said shoe and having second contacts thereon for coupling to said LED through said externally mounted first contacts to cause said LED to be selectively illuminated by said circuit.
