1. A light emitting flare device comprising:
a housing;
one or more light emitters positioned to emit light from the housing;
a battery;
wireless flare-to-flare communication apparatus; and
control circuitry;
wherein the wireless flare-to-flare communication apparatus is configured to receive signals from one or more others of the light emitting flares and the control circuitry is configured to receive information from the wireless flare-to-flare communication device and to cause said one or more light emitters to emit light in a synchronous pattern with light being emitted from said one or more neighboring light emitting flares, without requiring reference to a common reference signal;
wherein the control circuitry is further configured to perform a battery status check; and
wherein said one or more light emitters is/are configured to emit light in a top emitting mode and a side emitting mode, and the control circuitry includes a switch for switching between said top emitting mode and said side emitting mode.
