The power consumed by a light source associated with a device can be reduced by selectively influencing the activation and deactivation of the light source. A label associated with a unit of content that is "playable" on the device can selectively influence the activation and deactivation of the device. By a way of example, a light source associated with a satellite radio could automatically turn on when a new song starts to play. Different embodiments can involve vastly different types of content, remote devices, and activation/deactivation triggers.
