Exterior stairway lights should shine down toward the risers so that the stair treads will not be shadowed and cause a tripping hazard. Permanent and temporary lights are rated by watts. It is important not to overload house circuits. A 20-amp single circuit should not be loaded to more than 1600 watts. It is recommended that all decorative lighting be controlled by an accessible switch or circuit breaker and, when extension cords are used, they should be of the heavy-duty usage style and be of the grounding type.
Decorative lights add dimension and mood to exterior spaces and structures.
