SOURCE: Have a 2004 Peterbilt 379, looking for Specs for

Have a look at this site, it gives a comprehensive description for setting headlights:-

However, headlight adjustment must conform to the relevant road ordinances and laws of the place of vehicle registration. For your own peace of mind and to comply with legal requirements I suggest that you take the vehicle to a registered center and have the lights set to the standards set by law.

SOURCE: Have a 2004 Peterbilt 379, headlight setting is

Yes, if you are running over- the- road just stop in a State that has vehicle inspections and they can set the lights to their specs. In those States that have an inspection setting the headlight aim is part of the job.

Next method, park your unit about 20 feet from a garage door or the side of a building or carwash. Use some tape or pencil and make 2 crosses. The passenger side is allowed to be high and slightly to the right. A correctly aimed right headlight will focus on the curb or lane marker with the right headlight spot-on the lane marker. This will mean you will be safely within your lane on the right side of your truck as long as the headlight hits the lane marker.

For the left light it is suppose to be almost straight ahead and not tipped out to oncoming traffic. In some States the left light is turned slightly towards the center of your truck. You can check against the crosses you put on the surface of the building and watch the beams move as you adjust the lights. Use some chalk to mark where the tires were so you can get into the same spot.

I had to do some Vehicle Inspections in Texas years ago. I want to say the headlights were suppose to be 42" high at 20 feet, but you have a Peterbuilt. And now some of the cars are barely 48" high.

SOURCE: Air valve leaking air thru it when u release

If it's the same air valve that releases the parking brake then replace it so the brakes won't drag because of low air pressure. Air is APPLIED to release the brake so if the system air pressure starts to go low the parking brake will start to apply. This will eventually cause the brake drum to overheat and possibly start a tire fire.
