Halogen headlights have a single bulb for both hi and lo beams until the 2013 models then from 2014, a headlamp has two bulbs for the two beams. First, take out the cable that was connected to the negative aspect of the battery pole. To get to the headlight bulbs, there is a need to pop the air filter housing on the left side. Third, unscrew the bulb cover on the rear portion of the housing of the headlight counter-clockwise. Subsequently, unscrew the bulb in anti-clockwise direction to separate it from the housing and pull out the electric connection plug. During the installation of the new bulb, make sure that the lugs on the operators of the bulb head go into the respective slots of the headlight casing, then fit in the bulb and twist it anticlockwise to lock into place. Do not touch the lamp with bare hands to avoid problems with overheating and, consequently, simple burnout of the bulb; if the bulb was touched, then use a piece of alcohol soaked in a piece of cloth to clean it. The process of installation is done in the real order of uninstallation, starting with the package and finishing with the application icon.

Remove the headlight housing and place it face down on a clean surface, using a towel or shop rag to protect the lens. Each headlight housing contains two bulbs: high beam and low beam. To access either bulb, turn the circular cover counterclockwise and pull it off. Remove the dust cover from the bulb you intend to replace, then disconnect the electrical connector. After disconnecting, rotate the bulb counterclockwise and pull it out, followed by rotating the bulb holder counterclockwise to remove it from the housing. When installing the new bulb, ensure the three lugs on the bulb holder mounting flange align with the three cutouts in the plastic housing, insert the bulb, and turn it clockwise. Installation follows the reverse order of removal, and avoid touching the glass of the new bulb; if contact occurs, clean it with alcohol and a soft cloth before installation.
