In short, most 2007 Yukon models with halogen headlights use H11 for the low beams and 9005 for the high beams. If your Yukon is equipped with factory HID headlights (common on the Denali trim or certain options), the low-beam bulb is D2S. Always verify with your owner's manual or by inspecting the current bulb to account for trim or regional variations.
The 2007 GMC Yukon offered both halogen reflector headlights and optional HID projector headlights. The exact bulb type depends on your trim level and whether the vehicle was fitted with the HID upgrade. Below are the typical configurations and how to identify them.
Halogen headlight setup (common on base trims)
The following list covers the standard halogen configuration you’re likely to encounter on many 2007 Yukons. Before the list, note that these are the typical bulb types used in halogen headlamps for this model year.
- Low beam bulb: H11
- High beam bulb: 9005 (HB3)
In halogen configurations, replacing bulbs is straightforward: use H11 for the low beam and 9005 for the high beam, matching the factory design. This setup is common on base and some mid-level trims without HID headlights.
HID headlight setup (optional on some trims)
For Yukons equipped with factory HID headlights, the low-beam bulb type changes to a dedicated HID bulb and ballast. This section covers the typical HID configuration found in many 2007 Yukon models, including Denali variants.
- Low beam bulb: D2S (for projector HID assemblies)
- High beam bulb: Often part of the HID bi-xenon system or a separate high-beam design, depending on the exact headlamp assembly; verify with the owner’s manual or by inspecting the ballast/bulb arrangement
In HID-equipped Yukons, expect D2S bulbs for the low-beam projector. The high-beam arrangement can vary: some bi-xenon setups rely on the same HID assembly for both states, while others use a separate high-beam bulb. Always confirm the exact configuration for your vehicle by checking the manual or the current bulb.
How to confirm your exact bulb type
To be certain of your bulb type, compare the current bulb in place or consult official documentation. Steps include:
- Check the owner’s manual or the factory window sticker for headlamp specifications.
- Carefully remove the headlight bulb to read the bulb number printed on the base.
- Match the bulb’s shape and base to the replacement part at a trusted parts retailer or dealer.
Tips: handle halogen bulbs with gloves to avoid skin oils on the glass, which can shorten bulb life. If you’re unsure, a dealership or professional installer can confirm the exact bulb type for your trim and production date.
Summary
For the 2007 GMC Yukon, halogen-equipped models typically use H11 for low beams and 9005 for high beams. If your Yukon has factory HID headlights, the low-beam bulb is usually D2S, with the high-beam configuration varying by design. Always verify with the owner’s manual or by inspecting the bulb to ensure you purchase the correct replacement for your specific vehicle.
