The present invention relates to an intracavity system and method for illuminating a surgical site within a body cavity to be used with a stationary surgical device. The system comprises at least one light source comprising a light-emitting diode configured and operable to emit illumination light into the body cavity. The light-emitting diode is mounted on a coupling assembly for securing the light-emitting diode to an external surface of the stationary surgical device to permit selectively fastening the light source to any desired location along the stationary surgical device and repositioning thereof. Each of the at least one light source is connected via a wire to a handheld self-contained electrical power supply unit. The wire is configured to transmit power supply energy from the power supply unit to the light source.
