What is necessary to illuminate the entrance steps of a bus?

The requirement for illuminating the entrance steps of a bus revolves around ensuring passenger safety and accessibility, especially in low-light conditions. Step lighting is specifically designed to provide adequate illumination for the steps, making it easier for passengers to see and navigate as they enter or exit the bus. This lighting helps prevent slips, falls, and other accidents that could occur when people cannot clearly see where they are stepping.

Step lighting is strategically placed to focus on the area of the steps, directly addressing the key need for visual guidance at the entrance. While other lighting options, like interior lights or daytime running lights, may contribute to overall visibility, they do not specifically target the area of the entrance steps. Emergency flashers serve a different purpose, primarily to warn others of a stopped or disabled vehicle, rather than providing guidance for entering or exiting a bus. Thus, step lighting is the ideal solution for this situation, promoting safety and clarity while boarding or alighting from a bus.
