How to Change the Light Bulbs on a QX4
by Kurt Erickson
Replacing the headlights on an Infiniti QX4 takes a few extra steps if you want the job to go smoothly. When replacing the passenger side bulb, remove the battery in order to gain easier access to the headlamp assembly. On the driver's side, disconnect the air box cleaner to free up work space for this task. No matter what side you are working on, disconnect the battery terminals before beginning this task. Replacement headlights for the QX4 can be purchased at auto parts retailers.
