Headlamp: Description and Operation

GENERAL INFORMATION
LH vehicle headlamps are equipped with a bubble level to aid up/down headlamp alignment. The bubble level is used to assist headlamp alignment when compensating for vehicle ride height changes due to heavy luggage compartment loads or vehicle ride height changes. The vehicle should always be on a level surface when headlamp alignments are checked or changed. Headlamp alignment should always be first attempted by using the bubble level.

The bubble levels cannot be calibrated. The bubble level adjustments are set by the manufacture. Horizontal alignment does not ordinarily have to be changed except in the case of body damage or tampering.
