Halogen Headlights Pair for Buick LaCrosse (2005-2007) and Buick Allure (2005-2007)

Installation: Buick LaCrosse (2005-2007) and Buick Allure (2005-2007)

On the 2005-2007 LaCrosse and Allure, the front bumper cover or the bumper corners typically come off so you can reach the lower headlight fasteners. Professional installation and beam aiming are recommended. Switch off the lights and ignition, set the parking brake, and disconnect the negative battery cable before you start.

1. Open the hood. Remove the bumper-cover fasteners and pull the cover or the corners forward enough to reach the lower headlight bolts.
2. Remove the bolts that hold each headlight. Pull the assembly forward and unplug the factory connector. Do not pull on the wiring.
3. Install the included H11 bulbs in the new housings. Connect the factory-style connector, seat each assembly, and start the bolts. Repeat on the other side.
4. Reinstall the bumper cover, reconnect the battery, and test low beam and high beam. Aim the lamps on a level surface before driving at night.

Frequently Asked Questions

Which vehicles do these headlights fit?
2005-2007 Buick LaCrosse and 2005-2007 Buick Allure (the Canadian-market name for the same car). They will not fit 2008-2009 LaCrosse, which uses a later housing. Compare your current lamps with our photos before ordering.

No. 2008-2009 LaCrosse uses a later headlight. This pair is the 2005-2007 lamp only.

Are these a pair or a single lamp?
This is a complete driver and passenger pair, not a single-side lamp.

Do they include bulbs?
Yes. H11 halogen bulbs are included for both assemblies.

How are they installed on a 2005-2007 LaCrosse or Allure?
On this generation, the front bumper cover or the bumper corners typically come off so you can reach the lower fasteners. Remove the headlight bolts, unplug the harness, install the new lamp with the included H11 bulbs, reconnect, reinstall the bumper, and aim the lamps before nighttime driving.
