An alignment system for hitching a towing vehicle to a trailer is provided to increase the convenience and ease to the vehicle driver. A vertical trailer guide is temporarily joined to the tongue of the trailer proximate the hitch, and a guide receptor is affixed to the rear of the towing vehicle. A color indicator signals the driver when the vehicle and trailer are properly aligned, whereupon the driver can then manually complete the hitching operation.
