Emergency lighting

Emergency lighting is used on UNSC starships or installations when the main power is down or during battle. Emergency lighting is usually powered by a separate generator so that it does not draw off the main reserves. It is most essential that these lightings are used on the bridge, as combat situations will quickly get worse if the crew is unable to see what is going on.

An example of this is seen on the bridge of the cruiser, Pillar of Autumn during the Battle of Installation 04.
