This 2006 Cadillac CTS bulb size page helps you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing a headlight, a tail light, or a small interior lamp, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The 2006 Cadillac CTS used different bulb types depending on the lamp position, and some setups also vary by trim, lighting package, market, and body style. Use this page as a quick reference for the most common exterior and interior bulbs on the CTS, including low beam, high beam, brake, reverse, license plate, and cabin lights.
For best results, compare the bulb listed here with the one already installed in your car before ordering, especially if your CTS has optional HID headlights or a different lighting package. Halogen and LED replacements can look similar but may not fit or function the same way, and some aftermarket LED conversions need extra parts or may not be road-legal in every area. If your vehicle has been modified, or if a previous owner changed a lamp assembly, the installed bulb may differ from the original factory specification. Checking the old bulb, the socket, and the housing before purchase is the safest way to confirm fitment.

Yes. Trim level, lighting package, market, and body style can affect the exact bulb setup, so it is smart to confirm the installed bulb before buying replacements.
Yes, many positions can be upgraded to LED, but fitment and performance can vary. Some LED bulbs may need resistors, adapters, or CAN-bus compatible designs to work correctly without warnings or hyperflash.
Check the headlight assembly and the bulb already installed. HID-equipped cars use D1S low beam bulbs, while halogen-equipped cars use 9006XS low beam bulbs.
Use the chart as a guide, but always verify the bulb in the vehicle when possible. This is especially important if the car has been modified or if the lamp assembly was replaced in the past.
