An imaging system for a vehicle includes a tail lamp assembly that illuminates a field of illumination rearward of the vehicle. A light source control may operate at least one light source of the tail lamp assembly in a repeating cycle that includes (i) a first illumination period wherein light emitted by the tail lamp assembly has a first brightness level and (ii) a second illumination period wherein light emitted by the tail lamp assembly has a second brightness level that is lower than the first brightness level. A camera is operable to capture image data representative of a region that is at least in part within the field of illumination. A camera control may operate the camera to capture image data during at least part of the first illumination period.
