Lighting requires mindful planning. It’s not enough to have one overhead light in the garage, or one light pole to light up a driveway. Single lights tend to cast shadows and are potential sources of glare. The use of multiple lights can fill in areas that would otherwise be in shadows. Triggering them to turn on/off automatically (or hands-free) via motion-activated switches or a timer contributes to ease-of-use and security.
Poor lighting can be a major safety issue. It’s difficult to navigate a parking area without enough light. Shadows can hide possible barriers. Individuals who have difficulty with vision and/or decreased balance need to see where they are walking to make sure they are able to avoid obstacles and potential harm. Evenly-lit parking areas are essential. Think through the ways that shadows might exist, perhaps due to a light above a tree, or if someone gets in/out of the side of a vehicle opposite from a light.
