In this segment, Andrew adjusts the aim of the HID headlights that were installed on the car. It’s important to aim the bulbs at the right level because they are extremely bright and could be dangerous to drivers in oncoming traffic.Materials and tools used in this episode:
HID headlight kit, which should include all needed electronics and mounting hardware:
2 high-intensity discharge bulbs
Relays
Crimpers
Connectors
WiresStandard mechanic's shop tools (wrenches, sockets, ratchets, screwdrivers, etc.)
Drill
Drill bits
Marker
Wood
25 mm hole saw
Regular shop tools
Electrical tape
Safety goggles
Gloves
Aiming Headlights- Choose a location on level ground in front of a blank wall or garage door and position the vehicle so it's perpendicular to the wall and about 25 feet back (figure A).
- A laser-pointing tool (figure B) can help you align the car and mark the tire locations on the wall for reference.
Measure and mark the distance from the center of one headlight to the center of the other (figure C), and also measure the distance from the center of each headlight to the ground.Use electrical tape to mark the centerline between the tire marks, and then measure half the distance between the headlights on either side of center. Mark a tall vertical light for each headlight (figure D).
Mark those lines at the distance you measured between the headlights and the ground on the car, and run a horizontal line across the marks (figure E).Turn the headlights on low and see how they look. For a car with halogen bulbs, you would want the beams to be centered on the crossbars, but since the HIDs are so powerful, it's preferable to be just below the mark (figure F).
If the lights need to be adjusted, open the hood and locate the vertical and horizontal adjustment screws on the headlight housings (figure G). Adjust the lights until they line up correctly (figure H), and you’re good to go.
Note: This method will give you an approximate adjustment. To have your headlights aligned precisely, take your car to an auto service center.
