Retailers that carry outdoor dusk to dawn lighting fixtures include The Home Depot, Lowe's and Walmart. The online retailers Lamps Plus and Wayfair also carry dusk to dawn lights.
Dusk to dawn lights have built-in sensors that react to the lighting conditions outdoors. The lights automatically come on at dusk, stay on all night, and turn off at dawn. They are designed to increase safety outside of a home and to deter burglars.
Dusk to dawn lights come in a wide range of styles, from utilitarian flood lights to decorative wall sconces. Most models mount to an exterior wall of a house or garage.
