A light assembly for a school bus. The light assembly includes a housing having a front side and a rear side, wherein the rear side is mountable to a school bus. The front side of the housing includes a perimeter light, a stop light, and a platform light, wherein the lights can alert vehicles approaching a stopping school bus. The perimeter light is disposed around a perimeter of the housing and can produce an amber color. The stop light includes the word ‘stop’ in a non-colored transparent material and the platform light, disposed between the perimeter light and the stop light, can produce a red color. In one embodiment, the light assembly is operably connected to a control, speedometer, and door assembly of a school bus, allowing the light assembly to automatically activate when the school bus stops and automatically deactivate when the school bus door closes.
