This 2006 GMC Yukon bulb size guide is designed to help you verify the correct replacement bulb by lighting position, so you can match the right part to the right socket. Whether you are replacing a headlight, brake light, courtesy lamp, or interior bulb, this page organizes the common bulb types used on the Yukon in a simple, year-specific format.
Because trim and lighting equipment can vary, the exact bulb used on your 2006 Yukon may depend on the model, body style, and package. Use the bulb chart on this page as a fitment reference for the specific light location, then compare it with the bulb already installed in your vehicle before buying replacements.
For best results, confirm whether your Yukon uses halogen or LED lighting before ordering, especially on exterior lamps where previous owners may have made aftermarket conversions. Some positions can differ between SL and Denali versions, and certain interior or courtesy lights may have more than one listed option. If you are upgrading to LED bulbs, make sure the replacement is compatible with the housing and does not create fitment, polarity, or warning issues. When in doubt, remove the old bulb and compare the base, shape, and wattage marking before purchase, since even similar-looking bulbs can vary by trim and market.
The bulb chart lists 9005 for the high beam headlight bulb. For low beam headlights, the SL uses 9006, while the Denali uses 9005 for low beam.
Yes. The Denali low beam headlight bulb is listed as 9005, while the SL low beam headlight bulb is listed as 9006.
For the SL trim, the front turn signal bulb is listed as 3157A.
For the Denali trim, the front parking light bulb is listed as 3157.
The brake light bulb and tail light bulb are both listed as 3157R.
The back up reverse light bulb is listed as 3157.
The license plate light bulb is listed as 194 or 7441.
The glove box light bulb is listed as 194 or 7441.
The page lists several interior options, including 578, 211-2, and 161 depending on the specific dome or map light position and trim configuration.
The front fog light bulb is listed as 880.
The daytime running light bulb is listed as 4114.
Not always. The page shows multiple courtesy light options, including 168/917, 561, and 2721, so the correct bulb depends on the exact location and trim.
Because trim, lighting package, and prior repairs can change the bulb used in a given socket. Checking the installed bulb helps confirm the exact fit before you buy a replacement.
Often yes, but fitment depends on the housing and the bulb position. Some LED conversions may need proper compatibility, and the physical size or connector should still match the original bulb type.
