Abstract: An indicator device for detecting the presence of another device and alerting a user of the indicator device may comprise a housing, an electrical power source, a proximity sensor configured to detect the presence of the other device, and one or more indicator elements operable to alert the user of the indicator device where the proximity sensor is configured to operate the indicator element if the distance between the indicator device and the other device is below a predetermined value. The proximity sensor may be configured to operate the indicator element if the distance between the indicator device and the other device is within a predetermined distance.
