Whether you are changing a headlight, a tail lamp, or a small interior bulb, matching the bulb to the correct location is the easiest way to avoid fitment mistakes.
The Escalade uses a mix of exterior, interior, and cargo-area bulbs, and some positions may differ by trim, market, or lighting package. Use the bulb chart on this page as a position-by-position guide for the 2004 Cadillac Escalade, especially when you are comparing front lighting, rear lighting, and cabin lights.
Fitment can vary on this model depending on trim and equipment, so it is smart to confirm the installed bulb before ordering, especially if the vehicle has been modified or converted to aftermarket lighting. Some positions use halogen bulbs, while others may be LED or specialty types, and headlight or fog light upgrades can change the required bulb or connector style. If your Escalade has had previous repairs, swapped housings, or an aftermarket conversion, check the bulb currently in the socket and compare it with the chart before purchase.
