The 2017 Cadillac XTS uses a mix of LED and replaceable bulb types, and the exact fit can vary by lighting position, trim, and market. This page helps you verify bulb sizes by lighting position so you can match the correct replacement before you buy.

If you are replacing a headlight, taillight, interior lamp, or license plate bulb on a 2017 Cadillac XTS, checking the bulb chart by location is the safest way to avoid ordering the wrong part. It is especially useful when the same model year may use different lighting setups depending on equipment level.

For best fitment, compare your vehicle’s trim and lighting package with the bulb positions listed here, since Cadillac used LED assemblies in many exterior locations and different bulb types in some interior and auxiliary lamps. Some owners may see halogen-style service bulbs on certain markets or body styles, while others will have sealed LED units that are not serviced as a simple bulb swap. If you are considering an aftermarket LED conversion, confirm compatibility with the socket, polarity, and any required resistors or adapters. Before purchasing, remove the installed bulb and read the number on the base whenever possible, because that is the most reliable way to confirm the correct replacement for your specific 2017 XTS.
