Night lamps

People often use nightlights to provide a sense of security from light, or to relieve dysphobia (fear of the dark), especially in young children. Nightlights also benefit the public by revealing the general layout of a room without having to turn the main lights back on, avoiding tripping over stairs, obstacles, or pets, or marking emergency exits. Exit signs often use tritium in the form of a traser. Homeowners can place a nightlight in a bathroom to avoid turning on the main light fixture and having their eyes adjust to the light.
