Frequently Asked Questions
Will this 2011 Buick LaCrosse headlight fit other model years?
Yes, this headlamp assembly fits 2010-2016 Buick LaCrosse models with halogen lighting option TT4. Always verify your vehicle’s option code before ordering to ensure proper fitment.
What’s the difference between halogen and HID headlights on the LaCrosse?
Halogen headlights use traditional bulbs and have different housing designs than HID (High Intensity Discharge) systems. This is a halogen assembly and will not work with vehicles equipped with factory HID lighting.
Do I need to replace headlights in pairs?
While not required, replacing headlights in pairs ensures even light output and color matching. If your other headlight is showing signs of clouding or dimness, consider replacing both for optimal visibility.
Is this headlight assembly DOT approved?
Yes, this is an original equipment manufacturer (OEM) part that meets all Department of Transportation safety standards. It provides the same light distribution and performance as when your vehicle was new.
What bulbs does this headlight assembly use?
This LaCrosse headlamp uses standard halogen bulbs for low beam, high beam, and turn signal functions. The exact bulb types can be verified in your owner’s manual or by contacting us with your VIN.
How do I know if my LaCrosse has option code TT4?
Option code TT4 indicates halogen headlights and can be found on your vehicle’s RPO (Regular Production Option) sticker, typically located in the glove box or spare tire area. You can also contact us with your VIN for verification.
