Proper low beam pattern?
From : jmc
Q: 2001 dakota 4x4 ive suspected its been off since the beams were adjusted it returned from overseas where they drive on the wrong side of the road. this morning heavy fog i could hardly see my low beams meet at a point some distance in front and to the right side of my truck - actually off the right edge of the road. at about headlight level - so they are adjusted straight out or only slightly down. im not good at distance calculation but im guessing theyre meeting at a point in the air that they should be touching the ground at. are they even *supposed* to be meeting at a point so i took it back to the shop that did the adjustment and some rude little old man insisted that they were right because the machine said they were right. i suspect that the machine was set wrong for the height of my truck but i could see the futility in arguing with him so i just took my truck and left. i know another mechanic i can take it to. bah! does anyone have a photo or graphic or can describe of what the low beam pattern should look like am i wrong jmc .
