This 2019 GMC Yukon bulb size page helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. The Yukon was offered with different lighting setups, and the exact bulb type can depend on trim, package, and body style.
Use this guide to check common exterior and interior bulb locations on the 2019 GMC Yukon, including headlights, brake lights, turn signals, reverse lights, license plate lights, dome lights, map lights, and cargo area lighting. It is a practical reference when you want to replace one bulb or confirm the full vehicle setup.
Fitment can vary on the 2019 GMC Yukon depending on market, trim level, and whether the vehicle has halogen or HID headlights. That matters most for the low beam, since halogen-equipped models use H11 bulbs while HID-equipped models use D3S bulbs. Some lighting positions are listed as LED, which may mean the assembly uses an LED module rather than a simple replaceable bulb. If you are considering aftermarket LED or HID conversions, make sure the housing, connector, and beam pattern are compatible with your Yukon. The safest approach is to check the bulb already installed in the vehicle before ordering, especially for exterior lamps and any light tied to a specific package or option group.
It helps you confirm bulb sizes by lighting position, such as headlights, tail lights, reverse lights, license plate lights, dome lights, and other exterior and interior lamps.

Yes. Checking the installed bulb is the best way to confirm fitment, especially for lamps that vary by trim or for vehicles with optional lighting packages.
Aftermarket LED conversions may work in some positions, but they need to fit the housing correctly and produce the right beam pattern. Always verify compatibility before buying.
