A tap light is a small, portable lighting device that operates by being tapped or pressed to turn it on or off. When in operation, a tap light typically emits light, providing illumination in dark areas. These lights can be used for various purposes, such as in closets, on stairways, or as a nightlight.
Most tap lights use LED bulbs, which are energy-efficient and have a long lifespan. They may be powered by batteries or plugged into an outlet, depending on the model. When activated, a tap light can either stay on continuously or may have a timer that turns it off after a set duration. In summary, when in operation, a tap light serves to provide convenient illumination with simple activation.
