1st Gen Lighting Adjustment

Since I've thrown sandbags in the back for the winter, I've adjusted my headlamps for the season.
According to the manual, the lamps should be angled 0.4 degrees down from horizontal. They mention a .823" drop for a distance from wall of 9.84', of course conversions from metric.
I laid this out in Cad based on the 0.4 degree angle to find the distance for an even 1" drop. the result is 11.94' (11 15/16") which is close enough to 12'.
So that's a little more manageable, 1" drop = 12' away.
Also, the small hex adjustment screw requires a 4mm socket. Turning towards the drivers side(counter-clockwise) lowers the beam, turning towards passenger's side (clockwise) raises the beam. It is also recommended if you need to lower the beam, go past the point and tighten back to desired level.

***01.27.12**
Since this post, I found I had to adjust the beams to slightly lower than 1" at 12' to effective illuminate the road due to a 3" lift. The above works great for non-lifted trucks.
On the hex head, the 4mm fits well, however, I had to scotchbrite the hexhead a little to knock some rust off to fit the socket properly.

A stubby socket wrench like this works well.

 

Thank you for the Post! Need to adjust my headlights, way to high.

 

Could someone post a photo of where the adjustment screw is on the headlight housing? Would be good for future reference. Thanks.

 

I'll go shoot a picture and add it to the post

 

Thank you sir.

 

Thanks for that.

 

If onkly my aftermarket headlights had these adjusters in them

 

Definitely Thanks for this. My shade tree mechanic friends wanted to take off the grill surround and started dismantling the headlight assembly till I told them to STOP and checked TW.

My headlights were way too high (spring sag I'm sure). Didn't do it scientifically. Just pulled up on a level floor about 3 feet from a white wall and marked the high point for both headlights then started adjusting them down. We went down about 1.5" each then waited for dark to try them. We had to bring them back up just a hair and now they're fine!

Once again Thanks!

 

If a light ( left or right ) is moving a little chances are you may need to keep adjusting.
My left light was wobbly. When I turned my light on for adjustment it was out of alignment with the right.
After adjusting the left to be even with the right ( while shining on the wall )
the left light no longer was loose.

 

Thanks Charles-
An E6 socket also works in place of a 4mm socket. Mine were way too high with my 5" allpro lift with SAS FJ60 front-end combo......brought them down nicely to where they should be. Thanks again.
