Abstract: A trailer alignment guide device facilitates alignment of a trailer behind a vehicle when backing the trailer up. The device includes a trailer coupled to a vehicle. At least one projector is coupled to the vehicle directing a beam towards the trailer. A reflector is coupled to the trailer reflecting the beam back towards the vehicle. A receiver is coupled to the vehicle and positioned to receive the beam after the beam has been reflected by the reflector. The receiver detects a position of the beam being reflected back onto the receiver. A processor is communicatively coupled to the receiver and programmed to calculate a directional instruction for aligning the trailer behind the vehicle using the position of the beam reflected back on the receiver. A display coupled to the vehicle displays the directional instruction.
