A light bar assembly can comprise an elongated housing mountable to a roof of a motor vehicle and comprising a plurality of light transmissive sections. The light bar assembly can further comprise two or more light sources disposed within the elongated housing, and one or more sensors disposed in an interleaved configuration with the light sources. The light bar assembly can further comprise a controller communicatively coupled to the light bar via a wired interface including data wires and electric power wires. The data wires can be communicatively coupled to the sensors. Each sensor can be configured to output an electrical signal responsive to detecting a physical object within a spatial sector. A projection on a surface sustaining the motor vehicle of each spatial sector can be provided by a circle sector. The combination of all circle sectors can compose a sensing perimeter. In one embodiment, the sensing perimeter can be provided by a full circle with a center disposed within a projection of the motor vehicle onto the surface. Alternatively, the sensing perimeter can have an arbitrary shape configurable via a user interface.
