For the 2015 GMC Yukon, the high-beam headlight uses a 9005 bulb. Low-beam fitment depends on the headlight assembly: models with halogen headlights use H11, while models with HID headlights use D3S. Identify the headlight type before ordering, since these low-beam bulbs are not interchangeable.
The supplied fitment data lists LED lighting for several exterior functions, including the front and rear turn signals, brake lights, center stop light, daytime running lights, parking lights, side markers, tail lights, and rear turn signals. These applications are listed as LED rather than as replaceable bulb numbers.
- Reverse light: 921
- License plate light: 2825 or 98
- Vanity light: 6612F
- Interior lights: LED for dome, map, and trunk locations
For the most accurate replacement, match the bulb to the vehicle’s installed lighting configuration, especially for the low-beam headlights and license plate lamps.
