Aiming Your J.W. Speaker Headlights - High / Low or Low Beam Headlights
September 8, 2015
Proper alignment is important when installing new headlights. Each headlight must be securely mounted and properly aimed so the beam pattern “cut off line” complies with all applicable regulations. Follow our step-by-step guidelines for how to aim headlights properly when installing Low Beam or High / Low Beam Headlights.
We recommend that headlights are aimed with a headlight aiming system for proper alignment. If you are not familiar with the legal requirements for aiming your headlights, please see a professional service provider. Click here to download a PDF copy of the guidelines listed below.
Before Installation
We recommend getting your workplace ready before installation. Be sure that:
1. Vehicle is being aimed on a level surface.
2. All tires are properly inflated.
3. Vehicle is at normal driving height (applicable to listed vehicles).
NOTE: If a lift kit is added or removed from the vehicle, headlights MUST be AIMED AGAIN.
Required Supplies:
- Tape or chalk to mark lines
- Corresponding tools for your vehicle’s aiming mechanism
Optional Supplies:
- Laser level to expedite the aiming process and will help to
increase accuracy in aiming
Key Terms:
| Kink (elbow): The top of the pattern that is the cutoff when aimed at a wall. |
 |
| Alignment Point: The center of the angle in the Kink that must align to the center point when aiming the light at a wall. |
 |
| LHT (Left Hand Traffic): ECE Regulation countries like the United Kingdom |
 |
| RHT (Right Hand Traffic): DOT (and some ECE) Regulation countries like the United States |
 |
The following instructions are illustrated for RHT vehicles.Aiming for LHT vehicles will be mirrored to what is shown.
Aiming Guidelines:
| 1. Park your vehicle close to a wall, in an area where there is at least 7.62 meters (25 feet) of space behind it (excluding the car length). |
| 2. On the wall, draw a line from the ground to the approximate center point of the headlight. Repeat for the other headlight. This will create your Y axis lines. |
| 3. Connect the center points between headlights in a straight line, using chalk or tape. This will create your X axis (horizontal) line. NOTE: Use a straight edge and a level to make sure this line is straight. |
| 4. Extend your vertical, Y (vertical) axis lines up approximately 3 feet. Your lines should match the diagram below, when looking at the lines straight on. |
| 5. Reverse your vehicle in a straight line so that the front of the headlights are 7.62 meters (25 feet) back from the wall. |
| The goal of these instructions is to aim BOTH of your headlights so that the Alignment Point is at the cross section of the horizontal X and vertical Y lines you have drawn. The following directions illustrate the process and proper aiming of headlights. |
| 6. When you first turn on your vehicle after installing your headlights, the Alignment Points may be positioned differently than shown and will likely be aimed differently from each other. |
| 7. Using the alignment mechanisms in your vehicle, adjust one headlight vertically until the Alignment Point is even with the X axis. |
| 8. On the same headlight, adjust horizontally until the Alignment Point is even with the Y axis. |
| 9. Repeat this process on the other headlight. Both headlights should match the diagram below, where the Alignment Point is even with the point where the X and Y axis crosses. |
