This 2001 GMC Yukon bulb size page helps you verify the correct bulb by lighting position, so you can match the right replacement before you buy. Because the Yukon was offered with different trims and lighting packages, the exact bulb can vary between areas such as the headlights, parking lights, dome lights, and rear lamps.
Use this guide to compare the bulb type for each location on your 2001 GMC Yukon, including high beam, low beam, fog light, turn signal, brake light, license plate light, and interior lighting. Checking by position is the easiest way to avoid ordering the wrong part and makes replacement faster whether you are fixing one bulb or planning a full refresh.
For best fitment, always confirm your trim and package details before ordering, since SLE and Denali applications may use different bulbs in some positions. The 2001 Yukon also uses a mix of halogen bulbs and smaller interior bulbs, so LED upgrades may require a different beam pattern, polarity check, or load resistor depending on the location. Aftermarket conversions can work well, but they should be matched carefully to the housing and socket style. If possible, remove the installed bulb first and compare the base, connector, and markings before purchasing replacements.
The low beam bulb depends on trim. The Denali uses 9005 for the low beam listing on this page, while the SLE uses 9006. Always confirm the trim before ordering.

No. This page shows several possibilities, including 578, 211-2, 161, and 168/917 depending on the exact interior lamp position and original setup.
Check the trim, lighting package, and the bulb already installed in the socket. The 2001 GMC Yukon can use different bulbs for SLE and Denali applications, and some interior lights have more than one valid original bulb option.
Yes, in many positions you can, but fitment and performance depend on the housing. Headlights, fog lights, and signal lamps may need LED bulbs designed for proper beam control or additional hardware to avoid issues.
