Questions
What is the GMC Yukon XL low-beam bulb?
2019 GMC Yukon XL stores H11, D3S for the halogen low beam. Choose the LED headlight configuration separately when the chart lists one. These are not installed together.

Does the 2019 GMC Yukon XL chart include fog lights?
No fog-light bulb is stored for this year. This page does not add one.
How are HID bulbs handled?
D-series capsules such as D1S or D3S are HID. Exact catalog matches for those positions use HID products, not halogen bulbs.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
