A location assistance system includes a distress vehicle and multiple assistance vehicles. The distress vehicle broadcasts an emergency signal. The assistance vehicles are operable to receive the emergency signal, determine multiple distances to the distress vehicle, triangulate among the assistance vehicles to generate a spatial map of the distress vehicle relative to the assistance vehicles, determine one or more approximately horizontal lines in the spatial map that include the distress vehicle and at least one horizontally aligned assistance vehicle in response to the distress vehicle and the at least one horizontally aligned assistance vehicle being on a same vertical level in the spatial map, coordinate among the assistance vehicles to determine one or more horizontal sequences along the one or more approximately horizontal lines, and flash the of the assistance vehicles in the one or more horizontal sequences to lead toward the distress vehicle.
