Emergency lights are specialized lighting devices designed to provide illumination during power outages or emergencies. They are commonly used in buildings, vehicles, and public spaces to ensure safety and visibility. These lights can be powered by batteries or connected to a backup power source, allowing them to function when regular lighting fails. Typically, emergency lights are equipped with bright, energy-efficient bulbs, such as LEDs, which consume less power and have a longer lifespan. They are often installed in hallways, stairwells, and exit routes to guide people safely out of a building during emergencies like fires or blackouts.
