Cadillac Escalade 2009 Bulb Size
Bulb size chart
This page helps you find the right bulb sizes for the 2009 Cadillac Escalade by lighting position, so you can verify each exterior and interior lamp before ordering replacements. Because the Escalade could be equipped with different lighting packages, it is important to match the bulb to the exact socket and location on the vehicle.
For the 2009 Cadillac Escalade, the bulb chart includes common fitments for brake lights, tail lights, turn signals, side markers, license plate lights, reverse lights, dome lights, map lights, glove box lights, and more. Use the position-specific listings below to narrow down the correct bulb type for your trim and lighting setup.
Fitment can vary by trim, body style, market, and whether your Escalade uses halogen, HID, or LED lighting in certain positions. That means an aftermarket conversion may not use the same bulb as the original factory setup, especially for headlights and daytime running lights. Before buying, check the bulb already installed in your vehicle, compare the base style and connector, and confirm whether your model has LED headlights, HID headlights, or another package that changes the required bulb size.
