This 2004 Cadillac CTS bulb size guide is designed to help you verify the correct bulb by lighting position before you buy replacements. Whether you are changing a headlight, a tail lamp, or an interior bulb, matching the bulb to the exact location is the safest way to avoid fitment mistakes.
The 2004 Cadillac CTS uses different bulb types depending on the lamp position, and some trims or lighting packages can change what is installed. Use this page to compare the bulb chart for low beam, high beam, brake, turn signal, parking, license plate, and interior lights so you can narrow down the correct replacement quickly.
For best fitment, always confirm your CTS trim, body style, and lighting package before ordering, since halogen and HID setups use different low beam bulbs. If you are switching to LED bulbs, check the physical size, polarity, and space inside the housing, because some aftermarket LED conversions may not fit or may trigger warning issues. It is also smart to inspect the bulb already installed in the vehicle and compare the base style before purchase, especially on exterior lights where market differences and previous repairs can affect what is actually in the car.

Yes, many owners upgrade to LED bulbs, but fitment can vary. Check bulb size, housing clearance, and any electrical compatibility concerns before buying LED replacements.
Previous repairs, aftermarket parts, or market-specific equipment can mean the bulb in the car does not match the original listing. Checking the installed bulb helps confirm the correct base and size.
