apps/client/src/renderer/light-bars
The light bars' flashing (GAME_DESIGN §6.1, siren and light bar): each livery with a light bar has its two lamps (materials of the vehicle models, shared by every clone of that livery, so every bar of a livery flashes in step) and its pattern, a sequence of which lamps are lit, one step every so many milliseconds: the police's blue lamps in turn, the ambulance's red and white wig-wag with a double flash of both, the fire truck's reds in double flashes, one side then the other. A pure function of the time, so the pattern needs nothing on the wire.
