An electronic directional indicator includes a microcontroller in electronic communication with an electronic compass, an electronic motion-detecting module and at least one light source that is controllably illuminable. A battery life of the electronic directional indicator is managed by monitoring the electronic motion-detecting module for motion within pre-defined time periods and reducing power to electronic components accordingly. The electronic directional indicator can be placed on the face shield portion of a self-contained breathing apparatus face mask to provide a constant source of orientation for fire-fighters in reduced- or zero-visibility environments.
