INCREASED VISIBILITY OF INDICATING MARKERS IN A STRUCTURE AND ASSOCIATED SYSTEM AND METHOD

摘要

Disclosed herein is an indicating marker and method of use for removably attaching the indicating marker to a structure comprising an opening. The indicating marker comprises a cover device configured to removably seal the opening of the structure. At least one light is attached to the cover device. A power source is electrically connectable to the at least one light to emit a visible light from the at least light and illuminate the cover device. Alternatively, a wireless signal emitter is attached to the cover device and is configured to receive a signal from a wireless signal receiver separate from the structure and transmit a wireless response signal to the wireless signal receiver. In one example, both a light and a wireless signal emitter are attached to the cover device.
