摘要：
A tractor-trailer highway parameter gauge having visual indicators near the center of the field of view of an operator, which correlate with the location of the rearwardmost portion of the tractor-trailer within a traffic lane. The parameter gauge comprises a horizontally disposed base, a first electrically illuminated visual indicator mounted upon a first bracket assembly that is fastened to the base, a second electrically illuminated visual indicator mounted upon a second bracket assembly that is fastened to the base, an electrical component housing operatively connected to the first and said second visual indicators, and an electrical power supply connected to the electrical component housing. The parameter gauge enables safer operation of a tractor-trailer on a public highway.
