GMC Acadia Headlights

As part of General Motors’ plan to streamline its brands around a decade ago, it introduced the 2007 GMC Acadia in 2006 as a replacement for three of the company’s existing SUVs: the GMC Safari, the GMC Envoy, and the Pontiac Montana. It also marked GMC’s first venture into the SUV market. The Acadia met much success, and up to now, remains a staple in GMC’s SUV lineup.

With its large seating capacity and roomy interior, the GMC Acadia is an excellent family vehicle. Like all vehicles of its size, safety is utterly important for the Acadia. That’s why it’s essential to quickly repair or replace any part of the Acadia that compromises safety when damaged. One such component is your headlight.

If you notice that the output from your headlights is dimmer than usual or if it’s flickering, inspect your headlight assembly immediately. Dim, flickering, or non-functioning headlights might be caused by a blown-out bulb, bad wiring, or loose connections. All these are good reasons to replace the bad headlight components or even the entire headlight assembly.

Replacing your GMC Acadia headlights can also provide your SUV with a cosmetic upgrade. If you want a custom look for your vehicle, you can get a new headlight assembly with unique features, such as halo rings.

When you’re planning to replace your headlights, consider whether you just want to swap out the bulbs or if you want to replace the entire headlight assembly itself. If your only issue is a blown out bulb, replacing the bulbs on both headlights should solve the problem. Remember, it’s advisable to replace your headlights in pairs to ensure equal light output. If you have older halogen headlights and you’re looking to change the light source, you’re going to need to replace the entire headlight assembly.

Light Source

If you’re planning on swapping your old halogen bulbs for more energy-efficient and long-lasting options, it’s important to know the differences among the light sources. Here’s a brief rundown:

• Halogen - lasts for 500 to 1,000 hours; the most basic and budget-friendly light source.
• High-Intensity Discharge (HID) or Xenon - lasts around 10,000 hours; works almost the same as halogen bulbs, but lasts much longer because it utilizes xenon gas.
• LED - lasts around 30,000 hours; a highly efficient alternative and the modern-day vehicle’s favorite option.

Fit and Compatibility

If you’re just replacing the bulbs, make sure that you have the right bulb type. For instance, a 2008 GMC Acadia headlight assembly uses an H11 and H7 halogen bulb for the low beam and high beam headlights respectively. On the other hand, 2013 GMC Acadias use a 9012 halogen bulb for both low and high beam headlights.

Also, make sure that your Acadia actually uses halogen bulbs before purchasing a replacement. Other Acadias are actually outfitted with HID bulbs fresh off the factory. For example, 2011 GMC Acadia headlights can have either the H11 and H7 halogen bulbs or the D15 HID bulbs.

If you’re upgrading your stock halogen headlamps with a different light source, it’s also important to check for compliance on the replacement part as well. A DOT-compliant label on your replacement headlights will help you avoid any issues on the road.

Halogen replacement bulbs for the Acadia can cost as little as $10 to as much as $50 per piece. For the headlight assembly, prices range from a little over $100 to over $500 for a single piece.
