GM 91174687 Capsule / Headlamp / Fog Lamp Headlamp

Disconnect the negative cable from the battery. For the Samurai sealed-beam type, remove the front grille assembly, then take out the headlight retainer screws while ensuring the adjustment screws remain undisturbed; only loosen the screws that retain the bulb. On models with round headlights, loosen the screws enough to turn the retaining ring. Remove the retainer and pull the headlight out far enough to unplug the connector, then take out the headlight. To install, securely plug the connector into the new headlight, position it, and install the retainer and screws, tightening them securely before reinstalling the front grille assembly. For the Sidekick/X-90/Vitara and Tracker bulb type, open the hood and unplug the electrical connector. Reach behind the headlight assembly; on earlier models, grasp the bulb retaining ring and turn it counterclockwise to remove it, while on later models, detach the spring clip. Lift the holder assembly out for access to the bulb, push in and rotate the bulb counterclockwise to remove it, then insert the new bulb into the holder and turn it clockwise to seat it. Finally, install the bulb holder back into the headlight assembly.

A simple method for adjustment requires a blank wall 25 feet in front of the vehicle and a level floor. Vertical masking tape should be positioned on the wall to align with the vehicle's centerline and the centerlines of both headlights, along with a horizontal tape line for reference.
