Nissan 26261-89962 Bulb

Models equipped with halogen bulbs have separate headlight bulbs for the high and low beams. For low beam bulb replacement, first remove the rubber fender shield from the engine compartment to access the low beam headlight bulb; this step is not necessary for high beam bulb replacement. Next, twist the bulb holder counterclockwise and pull it out, ensuring to pull the bulb from the socket without handling the replacement with bare fingers. Unplug the electrical connector from the bulb holder, and then installation is completed by reversing the removal process.

The ignition process involves creating an arc between two electrodes, with a ballast module converting battery voltage to alternating current, stepping it up to about 800 volts AC, and the igniter controlling the voltage to start the light and then reducing it for normal operation.
