Lights: Emergency

Emergency lights are types of light designed to be useful in the aid of an emergency. They are battery backed lighting devices that turn on automatically during a power outage in a building. Emergency lights are standard in high occupancy and new commercial residential buildings. Most building codes require emergency lights to be installed and in older buildings as well.


There is an extensive range of emergency lights that differs in their own ways. They range from the avalanche beacons that are designed to attract the attention of emergency rescuers to the emergency lights utilized by drivers to alert passerby of the fact that they are seeking help due to vehicle problems.


Emergency lighting systems are quite valuable, it is a good idea to conduct routine checks on the system to ensure that they are still functioning. This also ensures that when in an emergency, the lights will serve their intended purpose instead of breaking down.


Emergency lights that are built into cars, boats, airplanes or trains typically run on a separate circuit from the rest of the electronics. They are designed in this manner to keep working even when power is lost, utilizing the backup power supplies.


Emergency lights on vehicles that are utilized for mass transportation are also often designed to click on in the event of an emergency, illuminating the exit signs so that people will be able to navigate their way towards safety regions. Emergency lights can also be used as warnings. In the case of “hazards” or case of car emergency, the lights will turn on when a car is disabled by the side of the road to alert other drivers of the fact that there is a problem.


In order to differentiate emergency lights from regular lights, they are sometimes of a different colour and may even inhibit a flash. The different colours of the lighting serve as an alert to people to the fact that there is an emergency occurring. Some colours are designed for high visibility even under the conditions where the view is obscured by dust, smoke and other particles.

The “emergency lights” are also typically referred to as portable lighting supplies that are designed for the use in an emergency. Some examples are like candles, flashlights and hurricane lanterns. These emergency lights can be pressed into service it the regular electrical power is lost. It can also be used to help people navigate to safety or to just provide lighting while others wait for the power to be restored. Several other sources of emergency lighting are also strongly recommended for emergency kits. This is so that lighting will be available in a hurry whenever it is needed.

Emergency lights can also be worn on like clothes. Snow gears and life jackets may also be equipped with emergency lights that can be activated with the push of a button or the pull of a string. This makes the wearer easy to identify during an emergency or while providing an emergency service. People going on outdoor adventures are highly recommended to use gears with emergency lights as these lights can be identified and seen from a distance. This will increase the chances of being spotted and rescued during the case of an emergency.

In early battery back up systems, emergency lights used were huge and dwarfed the size of the lights they provided power for. The systems typically used lead acid batteries to store a full voltage charge of 120. As technology developed further, the voltage requirements dropped gradually. The gradual drop subsequently caused for the size of the batteries to reduce as well. Modern lights are now only just as large as the bulbs and they fit quite well into the base of the fixture.
