A school bus having a pedestrian lighting system includes bus entrance door lamps that illuminate an area adjacent to the entrance door of the bus. Switch logic circuitry is connected to and controls bus door entrance lamp circuitry that provides power to the bus entrance door lamps. A power cutoff noise suppression switch, which otherwise functions to turn off noise generating devices in the bus when stopping for a railroad crossing, is connected to the switch logic circuitry or to delayed deactivation timer circuitry. The power cutoff noise suppression switch and the switch logic circuitry or the delayed deactivation timer circuitry are configured so that input of the switch logic circuitry to the bus door entrance lamp circuitry is overridden, and the at least one bus entrance door lamp is turned off, when the power cutoff noise suppression switch is activated.
