Buick Enclave 2015 Bulb Size
Bulb size chart
This 2015 Buick Enclave bulb size guide is designed to help you verify the correct replacement bulb by lighting position, so you can match the right part to the right socket before you buy. Whether you are replacing a headlight, interior lamp, or rear signal bulb, using the position-specific chart helps reduce guesswork and avoids ordering the wrong size.
The 2015 Buick Enclave uses a mix of LED and traditional bulb types depending on the lamp location, and some lighting details can vary by market, trim, or body style. Use this page to compare the bulb type for each exterior and interior light on the vehicle, including headlights, turn signals, brake lights, license plate lights, and cargo area lighting.
Fitment can vary between trims and lighting packages, so it is smart to confirm what is actually installed on your Enclave before purchasing replacements. Some positions may use factory LED assemblies, while others use halogen-style replaceable bulbs, and aftermarket LED conversions may require different parts or may not fit or function exactly like the original bulb. If you are unsure, remove the old bulb and compare its base and markings to the chart before ordering, especially for exterior lamps where beam pattern, polarity, and socket style can matter.
FAQ
What bulb does the 2015 Buick Enclave use for the low beam and high beam headlights?
The chart lists a D3S bulb for both the high beam and low beam headlight position. Always confirm the installed bulb and headlamp configuration before buying, since lighting equipment can vary by market or package.
What is the rear brake light bulb size on a 2015 Buick Enclave?
The rear brake light bulb is listed as 7443R. This is a specific fitment for the brake lamp position, so do not substitute it with a different 7443 variant unless you have verified compatibility.
What bulb fits the outer tail light on this vehicle?
The outer tail light bulb is listed as 7443R. If you are replacing the outer rear lamp, match the bulb to that exact position rather than using the inner tail lamp size.
What bulb is used for the inner tail light?
The inner tail light bulb is listed as 194, 7441. That is a different fitment from the outer tail light, so check which side and lamp section you are servicing.
What is the turn signal bulb size in the front?
The front turn signal light bulb is listed as 7444NA. Make sure you are replacing the front signal and not the rear signal, since the bulb sizes are different.
What bulb does the rear turn signal use?
The rear turn signal light bulb is listed as 7443. This differs from the rear brake light bulb, so it is important to identify the correct rear lamp function before ordering.
What size is the back-up reverse light bulb?
The back-up reverse light bulb is listed as 921. This is the bulb size used for the reverse lamp position on the 2015 Buick Enclave.
What bulb fits the license plate lights?
The license plate light bulb is listed as 168, 917. Either size may appear in the chart for this position, so compare the old bulb and socket before purchase.
Are the map lights and vanity mirror lights the same bulb size?
No. The map light bulb is listed as 168, 917, while the vanity mirror light bulb is listed as 6612F. These interior bulbs are not interchangeable by default, so check each location separately.
What bulb is used for the dome light?

What bulb fits the trunk or cargo area light?
The trunk or cargo area light bulb is listed as 194, 7441. This is a common interior cargo lamp size, but the exact fit should still be confirmed against the existing bulb.
What are the parking light and front side marker bulb sizes?

What bulb is used for the rear side marker light?
The rear side marker light bulb is listed as 194NA. That bulb is specific to the rear marker position and should be matched carefully when replacing it.
Does the 2015 Buick Enclave use LED bulbs anywhere?
Yes. The chart lists LED for the center high mount stop light and the daytime running light. These may be factory LED units rather than simple replaceable bulbs, so check the assembly before attempting replacement.
