I have a 2016 Dart SE. When i have the headlights on, there is a dark spot directly in front of the car and the beams go to the left and the right of the car. I know how to adjust the vertical but what about the horizontal? Does anyone else have a similar issue?

There is no horizontal adjustment.

If you pull up to a garage door, you should be able to see where the headlights point.

STANDARD PROCEDURE - LAMP ALIGNMENT

VEHICLE PREPARATION FOR LAMP ALIGNMENT

1.Check for and correct any burnt out bulbs.

2.Repair or replace any ineffective, worn or damaged body or suspension components that could hinder proper lamp alignment.

3.Verify the proper tire inflation pressures.

4.Remove any accumulations of mud, snow or ice from the vehicle underbody and clean the front lamp lenses.

5.Verify that there is no load in the vehicle (cargo or passengers), except for the driver.

6.The fuel tank should be FULL. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated gallon of missing fuel.

7.Verify the correct vehicle suspension height.

LAMP ALIGNMENT SCREEN PREPARATION
Wheel Vehicle Tire Car Automotive tire


The procedure that follows will prepare a suitable front lamp alignment screen.

1.Tape a line on a level floor at the appropriate distance away from and parallel to the flat wall that will be used as the lamp alignment screen. Refer to the Lamp Alignment Screen Distance table for the appropriate measurement. The level floor will be used as the horizontal zero reference.

2.An adjacent wall or floor member that is perpendicular to the alignment screen can be used as the vertical zero reference. If there is no adjacent wall or floor member that is perpendicular to the screen, tape a second line on the floor perpendicular to both the alignment screen and the first line, and outboard of either side of where the vehicle will be positioned. This will be used as the vertical zero reference.

3.Position the vehicle so that the side of the vehicle is parallel to the vertical zero reference, and so that the front of the lamp lenses are in the vertical plane of the parallel line taped on the floor 7.62 meters (25 feet) away from the screen.

4.Rock the vehicle side-to-side three times to allow the suspension to stabilize.

5.Jounce the front suspension three times by pushing downward on the front bumper and releasing.

6.Measure the distance between the optical center of one of the lamps being aimed (head or fog) and the floor (horizontal zero reference). Transfer this measurement to the alignment screen with a piece of tape placed horizontally to the floor. This line will be used as the lamp horizontal reference.

7.Measure the distance between the vertical zero reference and the optical center of the nearest lamp being aimed (head or fog). Transfer this measurement to the alignment screen with a piece of tape placed vertically across the appropriate (head or fog) lamp horizontal reference. This is the centerline reference for the first lamp.

8.Measure the distance on center between the first and the second lamp being aimed. Transfer this measurement to the alignment screen with a second piece of tape placed vertically across the appropriate (head or fog) lamp horizontal reference. This is the centerline reference for the second lamp.

HEADLAMP ALIGNMENT

NOTE:
Due to the linear nature of the headlamp cutoff, a properly aimed low beam headlamp will project the top edge of the high intensity pattern on the alignment screen just below the horizontal line to 50 millimeters (2 inches) below the horizontal line for domestic market vehicles. No horizontal (right/left) adjustment is required for this headlamp beam pattern in domestic market vehicles. The high beam pattern will be correct when the low beams are properly aimed.

1.Turn the headlamps ON and select the LOW beams.

NOTE:
On Chrysler models, a screwdriver is inserted through a guide loop molded into the back of the front lamp unit housing to assist in directing the screwdriver blade to the adjustment screw.

2.Use a screwdriver to rotate the headlamp vertical adjustment screw (2) on each front lamp unit (1) to adjust the beam height as required.


You may want to remove the front bumper and check to see if the headlight assemblies are installed correctly. If the car was in an accident, a bracket may have broken off. If you have aftermarket headlights, that may be the problem. There is a good you tube video by motor city mechanic for removing the bumper cover.
