Bulb size chart
This page helps you verify bulb sizes for the 2004 Cadillac XLR by lighting position, so you can match the correct replacement before you buy. The XLR uses a mix of LED and traditional bulb types depending on the lamp location, and the exact fit can vary by market and lighting package.
Use the bulb chart to confirm each exterior and interior light on your 2004 Cadillac XLR, including headlights, fog lights, turn signals, parking lights, license plate lights, and cabin bulbs. Checking by position is the easiest way to avoid ordering the wrong bulb for this model year.
For best fitment, compare the bulb listed on this page with the bulb already installed in your Cadillac XLR, especially if the car has been modified or if you are shopping for an aftermarket LED conversion. Trim level, package content, and regional equipment can change the bulb used in a given socket, and some lighting functions may differ between halogen and LED setups. If you are replacing factory bulbs, make sure the new bulb matches the base type and physical size, not just the wattage or brightness claim. When in doubt, remove the old bulb and check the number printed on the base before purchasing.
