Abstract
A communication system (100) formed of a portable radio (102) and radio accessory (106) is provided in which the accessory (106) provides emergency strobe and flashlight modes, the flashlight mode further providing a low battery indicator. Strategic control of lighting triggers and patterns allows for a single high intensity LED (132) to be used for both emergency strobe and flashlight modes, with minimized impact on battery life.
