Twin halogen bulbs accompany low and high-beam capabilities on 350Z vehicles during 2003 to 2005 respectively while years from the same period use a Xenon low-beam alongside a halogen high-beam but shielded under one protective housing. Only one Xenon high-and-low beam bulb exists in 2006 and all following Nissan Pathfinder models. HID (High Intensity Discharge) bulbs generate triple the light output of standard halogen bulbs while using reduced energy and maintaining a lifespan equal to ten times their standard counterparts. The system runs with an alternating current to ignite its xenon gas material exactly like vapor-filled streetlights although it needs a ballast module to convert power from the battery into the required alternating current. An HID bulb reaches operational temperature within 10 to 15 seconds dependent on the function of an igniter which controls the electrode voltage. To change bulbs customers must begin by removing the wheel lug nuts from the relevant wheel position then safely raise their vehicle before taking off both the wheel and the front section of the wheel well splash shield. Turn off the headlight switch then disconnect the battery terminal while lowering all windows before starting installation. Begin by removing the protective cover before checking the O-ring seal on halogen bulbs and then disconnecting the electrical connector and taking out the bulb by pressing the retainer wire. The installation involves aligning the holes on the lightbulb with the housing slots then fixing the retainer wire before proceeding with the bulb exchange steps.
