A track head unit includes a lighting device, a first sensor, a second sensor, one or more motors, and a controller. The first sensor is configured to receive transmissions from a portable remote control device. The second sensor is configured to receive transmissions associated with a target object. The one or more motors are mechanically coupled to the lighting device and are configured to position the lighting device along a first direction and a second direction. The controller is coupled to the lighting device, the first sensor, the second sensor, and the one or more motors. The controller is configured to receive a control signal from the remote control device via the first sensor, responsively transmit a locator signal to a locator that is disposed at a target object, receive a response signal via the second sensor from the remote object in response to the transmitting, and based upon the response signal, actuate the motors to aim the lighting device at the target object.
