Finishing Touches
Headlight alignment
TOOLS: Marker, masking tape, tape measure.
Note:
•
Make sure that the car is at the correct ride height before the alignment procedure is done. Ride
height should be 4 ½” at the front and 4 ½” at the back measured to the bottom of the 4” round
tube with the normal number of people/weight in the car.
•
It is important that the headlights are aimed properly in order for it to perform at their best. Lights
that are aimed incorrectly will not only perform poorly but may also offend oncoming traffic.
When replacing bulbs, it is a good idea to verify that your lights are properly aimed. Slight
variances in filament position can translate to large variances in beam pattern. The following
procedure does not require special aiming equipment and ensures proper aim.
1.
Find a flat level surface next to a vertical white wall where the car can be parked (a garage door is an
ideal location at home).
2. Pull the car straight up to the wall as close as possible.
3. Using masking tape and a marker, draw a vertical line on the wall corresponding to the centerline of
the vehicle.
4. Pull the car straight back until the headlights are 25 feet from the wall.
5. Make the following two measurements:
Measurement A: From the ground to the geometric center of one of the headlight lenses
Measurement B: From one of the low beam headlights to the vehicle centerline.
(Also measure from high beam center to vehicle centerline for 4 headlight systems)
Note these measurements.
