Abstract
The invention relates to improvements in trailer alignment and hook-up systems which are used with conventional hitching and hitch elements. The system comprises a fork-like sighting member attached to the towing vehicle and a flexible sighting pole assembly attached to the trailer hitch. The vehicles are properly aligned when the hitching element bumps the base or tail of the sighting pole causing it to vibrate while being viewed within the fork-like sighting member.
