This 2011 GMC Acadia bulb size guide is designed to help you verify the correct bulbs by lighting position, so you can match the right replacement to the right socket. Whether you are changing an exterior lamp, a cabin light, or a cargo-area bulb, using the correct fitment saves time and helps avoid ordering the wrong part.
The 2011 GMC Acadia uses different bulb types depending on the lamp location, and some lighting positions may vary by trim, market, or body style. This page organizes the common bulb sizes for the Acadia by function, making it easier to confirm what belongs in the headlight, turn signal, brake light, license plate light, and interior lighting locations.
For the best fitment, compare the bulb listed for your specific lighting position with the bulb already installed in your vehicle before buying replacements. Trim level, factory lighting package, and whether your Acadia uses halogen or HID-style lighting can change the correct bulb choice, especially for headlight and front signal applications. If you are considering an aftermarket LED conversion, make sure the new bulb matches the socket, clears the housing, and works properly with your vehicle’s electrical system. When in doubt, remove the old bulb and check the base style and markings first, since that is the most reliable way to confirm fitment.
The listed low beam headlight bulb for the 2011 GMC Acadia is H11. Some versions may also use a D1S setup for headlight applications, so it is important to confirm the exact lighting package on your vehicle before ordering.
The available bulb chart for this page lists D1S for the headlight bulb high beam and low beam position. Because lighting equipment can vary, verify the bulb installed in your Acadia before purchase.
The front turn signal bulb listed for this model is 12272NA. This position can vary by market or trim, so checking the existing bulb is recommended.
The rear turn signal bulb is listed as LED on this page. Since the exact LED replacement can depend on the lamp assembly, confirm the installed bulb or housing type before buying.
The brake light bulb is listed as LED. If your Acadia has an LED-equipped rear lamp assembly, the replacement may be different from a traditional replaceable filament bulb, so verify the assembly type first.
The tail light bulb is listed as LED. Because some Acadia rear lamps use integrated LED lighting, the exact replacement method may depend on the lamp design.
The license plate light bulb sizes listed are 168 and 917. Either size may be used depending on the exact lamp setup.
The dome light bulb listed for this vehicle is 212-2. Checking the old bulb is still a good idea, especially if the interior lamp has been changed before.
The map light bulb sizes listed are 168 and 917. These are common interior bulb sizes, but you should still confirm the one currently installed in your Acadia.
Both the parking light bulb and glove box light bulb are listed as 194 and 7441. These positions may use the same bulb family, but the exact fit should be confirmed by location.
The daytime running light bulb listed is 3157. This is a useful reference for owners replacing front lighting on the 2011 GMC Acadia.
Before converting to LED, make sure the bulb matches the socket, fits inside the housing, and works with the vehicle’s electrical system. Some LED upgrades may need additional components or may not be suitable for every lamp position.
