Introduction

This guide will show you how to replace the headlights on a 2005 Buick Lesabre. As is common knowledge, driving without functioning headlights is not only illegal in most areas, but is also dangerous.

In this guide, you will replace one or more XtraVision Headlight and Fog Light Bulb 9006XV-2 headlights. If you are replacing any low beam lightbulbs you will instead use XtraVision Headlight and Fog Light Bulb 9005XV-2 headlights. Typically, if one light has gone out, the other will follow soon so it is best to do the both at the same time.

Before beginning this repair, ensure that the car is off, and hasn't been running for at least 20-30 minutes. If the repair is performed immediately after the car has been shut off, the engine can retain a large amount of residual heat. This can lead to the possibility of suffering burns while attempting the repair. Avoid touching the glass of the headlight bulb as the oils and salt on your hands can weaken it over time and cause it to burn out more quickly or even shatter.

During step 5 of the guide, the headlight housing can fall out from the front of the car. This will damage the headlight wiring, possibly severing the power cables. To prevent this from occurring, be sure to keep hold of the housing while completing the repair. It may help to have an assistant for help.

Step 5

Loosen the housing by gently pulling it out toward the front of the car.
Once the housing has been moved, find the headlight terminal on the back of the housing.
This is the high-power headlight. If you are replacing a regular headlight, you will find it situated further toward the side of the car on the back of the housing.
Potential for device damage: If the housing is pulled too far, it can fall out of the car, possibly severing the headlight wires. Therefore, be careful to support the housing while performing the repair.
