This 2011 GMC Yukon bulb size page helps you verify the correct bulbs by lighting position, so you can match the right replacement before you buy. Whether you are changing a headlight, a license plate bulb, or an interior lamp, the goal is to make fitment easier and reduce guesswork.
Because Yukon trim and lighting equipment can vary, this page lists the bulb sizes shown for the 2011 model by location. Use it as a practical reference for exterior and interior lighting, including front, rear, cargo, and mirror lights.
Fitment can differ by trim, package, market, and body style, so always compare the bulb in your vehicle before ordering. Some 2011 GMC Yukon applications use halogen bulbs, while others may have LED lighting or different rear lamp configurations, especially on Denali and Hybrid versions. If you are considering an aftermarket LED conversion, make sure the bulb type, polarity, and physical clearance are compatible with the housing. When possible, remove the installed bulb and confirm the number printed on the base or glass before purchase, since that is the safest way to avoid ordering the wrong replacement.
