In the base model 2003 Infiniti G35 Sedan, the low-beam bulb is halogen and the high-beam and fog bulb is halogen; however, all other 2003 models and all 2004 through 2006 Sedans have Xenon low-beam bulbs and halogen high-beam and fog bulbs. Starting from 2007 MY, G35 Sedans use a single Xenon low-beam/ high-beam bulb having a tighter focus and higher intensity. The G35 Coupes that came from 2003 to 2005 have a Xenon low-beam bulb coupled with a halogen high-beam/fog light bulb Illumination while the G35 Coupes of the 2006 to 2007 models incorporate the use of a Xenon low-beam/high-beam bulb. A basic 2003 through 2005 Nissan 350Z uses two halogen bulbs, low beam and high beam, while other models from that period have a Xenon low beam bulb and a halogen high beam bulb; all these bulbs can be accessed using a single cover. During the same year, the models of 350Z also changed to a single Xenon as low beam/high beam bulb. HID headlight bulbs generate three times the light of normal halogen bulbs, requires lesser electric power and has a existence period ten times more than. They work using an AC with xenon gas similar to the gas in the vapor filled street lamp, but bare quick to warm up. Ignition is done by constructing an arc between two electrodes; a ballast transform the battery voltage to AC voltage of around 800V, the igniter regulates the voltage to fire the light then drops to the regular voltage. When it comes to bulb replacement, start by loosening the wheel lug nuts of the correct side, then jack up the car securely, next, remove the front wheel, as well as the front part of the wheel well splash shield. As with the previous step, be sure the headlights switch is off and the battery cable negative end removed, and that the windows have been lowered as on G35 Coupes and 350Z. For halogen bulbs, unscrew the bulb cover in the anti-clockwise direction, check the health of O ring seal and if damaged it has to be replaced. Remove the electrical connector from the bulb, rotate the retainer wire and get rid of the bulb and when replacing the bulb, locate the lobes of the tabs on the bulb into the slots of the housing, then secure the wire retainer, reverse the process to install the bulb.
