Cadillac Escalade 2011 Bulb Size
Bulb size chart
This 2011 Cadillac Escalade bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Whether you are replacing an exterior lamp, an interior courtesy light, or a headlight bulb, using the bulb location on this page makes fitment easier and reduces guesswork.
The 2011 Cadillac Escalade uses different bulb types depending on the lamp position and the lighting package. Some locations are shared across trims, while others vary with LED, HID, or other factory equipment. Use the bulb chart to confirm the exact bulb style for each area of the vehicle before ordering replacements.
Fitment can vary by trim, package, market, and body style, so it is smart to compare the listed bulb position with the bulb already installed in your Escalade. This is especially important for headlight and daytime running light setups, since halogen, HID, and LED-equipped vehicles may use different bulbs or assemblies. Aftermarket conversions can also change what fits, even if the original factory listing is different. If possible, remove the old bulb and check the number printed on it before purchasing a replacement.
