This 2009 GMC Yukon bulb size page helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Whether you are replacing a headlight, parking light, license plate lamp, or interior bulb, the fitment can vary by trim and lighting package, and this page organizes the common bulb sizes for the Yukon by location.
For the 2009 GMC Yukon, the chart includes exterior and interior bulbs such as H13 headlights, 4157NA front turn signal and parking light bulbs, 194NA side marker bulbs, and 212-2 interior bulbs for the dome, map, and cargo areas. It also lists different rear and brake light setups for Hybrid and Denali versions, which is especially useful when you need to confirm the exact bulb before ordering.
Fitment on the 2009 Yukon can change with trim level, body style, and market, so it is smart to compare the bulb in your vehicle with the listing before purchasing. If you are switching from halogen to LED, make sure the replacement is compatible with the socket, polarity, and any vehicle lighting controls, since some aftermarket LED conversions may need resistors or adapters to avoid warnings or fast flashing. When possible, remove the old bulb and check the base style and markings directly, especially for rear lamps and cargo or vanity lights where similar-looking bulbs can be easy to mix up.
