Jiggers Red, it's the cops! Quick, hide the stash and book it!!!!!
Somehow, we all knew this day would come. The day that we watch COPS to see redshifter running through backyards wearing nothing but a pair of ragged jeans, a tanktop, and a pair of Grados only to be violently intersected by the K9 unit.
The red light is called a beacon, and is required by the Federal Aviation Administration. It is required to be energized (on) whenever the master switch is on, indicating that the aircraft could start/run at any moment, and that there is a fire hazard possibility. Almost all other countries have adopted the same regulation.
