This 2009 Buick Enclave bulb size guide helps you verify the correct bulb by lighting position, so you can replace the right lamp without guesswork. Whether you are changing a headlight, interior bulb, brake light, or license plate light, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The Enclave uses a mix of exterior and interior bulb types, and some positions may differ by trim, lighting package, market, or body style. Use this page as a quick reference for the 2009 Buick Enclave and compare the bulb chart to the light you are servicing before you buy replacements.
For best results, confirm the bulb already installed in your Enclave before ordering, especially if your vehicle has optional equipment or has been modified with aftermarket lighting. Some positions may be halogen from the factory while others may use LED upgrades or LED-style replacements, and conversion kits can change fitment or beam pattern. Trim and package differences can also affect the exact bulb used, so checking the old bulb, the owner’s manual, and the socket style is a smart step before purchase.
The listed headlight bulb for both high beam and low beam is D1S. Always verify the installed bulb and headlamp type before replacing it, since lighting equipment can vary by market or package.
The front fog light bulb is listed as H11 LED or H16 LED. If your Enclave has aftermarket fog lights or LED conversions, confirm the socket and housing before ordering.
The rear brake light bulb is 7443R. This is separate from the turn signal and tail light positions, so it is important to match the bulb to the correct rear lamp location.
The rear turn signal light bulb is 7443. If you are replacing both rear signal bulbs, check both sides for consistent brightness and color.
The outer tail light bulb is 7443R. The inner tail light bulb is a different size, so do not assume both rear tail lamps use the same bulb.
The inner tail light bulb is 194, 7441. This is one of several interior and exterior positions on the 2009 Buick Enclave that use a smaller wedge-style bulb.
The back up reverse light bulb is 921. If the reverse lights are dim or out, replacing both sides together can help keep the rear lighting even.
The license plate light bulb is 168 or 917. These are common small wedge bulbs, but it is still a good idea to compare the old bulb before buying replacements.
The dome light bulb is 212-2. Interior bulbs can vary with trim and package, so check the dome lens and socket style if your Enclave has been changed from stock.
The map light bulb is 168, 917, and the glove box light bulb is 194, 7441. These interior bulbs are easy to mix up, so verify the location before ordering.
The daytime running light bulb is 3157. Because DRLs are used often, it is a good idea to inspect both sides and replace them as a pair when one fails.
The front parking light bulb is 2827, and the front side marker light bulb is also 2827. The rear side marker light bulb is 194NA, which is a different bulb type.
