"After having some repairs done at a local body shop, I noticed the low & high beams are out of adjustment. Apparently, the state of TX no longer requires proper aim as part of their inspection. Thus I cannot find anyone in the North Dallas/Plano area th

at has the proper aiming equipment. I've even called a few service/body shops with no luck.

Does anyone have an accurate DIY system of headlight adjustment?"

Solution: Tape Measure and flat wall (garage doors work) Up/Down Adjustment:
Park ~20 ft. from a flat wall on a level surface. Measure height of center of headlights. Measure height of light beam on wall.
Adjust low beam such that center of beam on wall is a couple of inches below center of headlight height.
Adjust high beam for level or slightly above level or as perferred.

Left /Right Adjustment:
Repeat above except measure separation between headlights. Measure separation of projected beams on wall. I adjust my right headlight bias slightly to the right for "Deer Search Mode".

Remember: With only two adjustment screws per light, the up/down/left/right adjustments are iterative as one affects the other.

I hope this aims you in the right direction.
