2022 GMC Yukon Bulb Sizes

Quick Reference

The 2022 GMC Yukon, a popular and robust full-size SUV, offers a mix of lighting technologies depending on the trim level. Many lower trims come standard with halogen headlights and fog lights, while more premium trims feature full LED lighting systems from the factory. It’s crucial to verify your specific trim level and existing bulb type before purchasing replacements or upgrades.

For models equipped with halogen headlights, the low beam commonly uses an H11 bulb, and the high beam uses a 9005 bulb. These are standard halogen bulbs that produce a warm yellow light. Higher trims and optional packages often include integrated LED headlights, which do not use replaceable bulbs for the low and high beams. Instead, the entire headlamp assembly contains the LED light source, meaning if an LED fails, the whole unit typically needs replacement. Similarly, the brake lights and tail lights are almost exclusively integrated LED units across all trims.

Fog lights on the 2022 Yukon can be either H11 halogen bulbs on base models or integrated LEDs on higher trims. The Daytime Running Lights (DRLs) and front turn signals are typically WY21W LED bulbs, offering a crisp, bright light. The rear turn signals generally utilize 7440A LED bulbs, while reverse lights commonly use 7440 LED bulbs. Most modern vehicles, including the 2022 Yukon, have transitioned to LED bulbs for exterior marker lights and interior lighting for improved longevity and efficiency.

License plate lights are usually 194 LED bulbs, and front and rear side markers often use W5W LED bulbs. For interior lighting, the dome and map lights (both front and rear) typically use 2825 LED bulbs, providing clear and efficient illumination inside the cabin.

LED vs Halogen Upgrade Considerations

Upgrading from halogen to LED bulbs in your 2022 GMC Yukon, especially in the headlights and fog lights, can significantly improve light output, visibility, and the aesthetic appeal with a whiter, more modern light. However, there are several key considerations.

CANBUS Errors: Modern vehicles like the 2022 Yukon use a Controller Area Network Bus (CANBUS) system to monitor various electrical components, including lighting. When you replace a halogen bulb with an LED, the LED bulb draws significantly less power. This lower current draw can trick the CANBUS system into thinking the bulb is out or malfunctioning, triggering dashboard error messages (e.g.,
