An apparatus for facilitating the alignment of a trailer hitch socket with the ball mounted on the towing vehicle is provided wherein a couple of interfitting masts are used. The first mast mounts atop the socket on the trailer tongue and extends vertically upward high enough to the point which it is visible from the towing vehicle. The second mast has a collar to engage it on the ball of the trailer hitch attached to the towing vehicle. It also extends upwardly to a height at which it is visible from within the towing vehicle. As the vehicle backs up toward the trailer, the driver can see the two masts and steer such that they will come closer and closer together and finally nest together when the socket is directly over the ball.
