This page helps you verify the bulb sizes for the 2004 Cadillac CTS-V by lighting position, so you can match the correct replacement before you buy. Because the CTS-V could be equipped with different lighting setups, checking the exact lamp location is the safest way to avoid ordering the wrong bulb.
Use the bulb chart on this page as a quick reference for exterior and interior lights, including headlights, turn signals, brake lights, license plate lights, and cabin bulbs. It is especially useful when you are replacing a single failed bulb and want to confirm the correct fitment for your specific CTS-V.
Fitment can vary by trim, package, market, and body style, so always compare the bulb position on your car with the listing on this page. The 2004 Cadillac CTS-V may use halogen or HID low beams depending on configuration, and aftermarket LED conversions can change the bulb type or require additional parts. Before ordering, check the installed bulb or the headlamp housing to confirm whether your car uses D1S, 9006XS, or another setup for that location. This is also a good time to verify whether the replacement needs to match the original filament style, color, or connector shape.

The high beam bulb is 9005XS.
The front fog light bulb is listed as 9145 LED.
The daytime running light bulb is 3157.
The front outer turn signal bulb is 2825, and the front inner turn signal bulb is 3157A.
The rear turn signal bulb is 3157A.
Both the brake light bulb and the tail light bulb are 3157R.
The back up reverse light bulb is 3157.
The license plate light bulb is 2825.
The front side marker light bulb is 194NA.
The rear side marker light bulb is 2825.
The center high mount stop light bulb is PC175.
Both the dome light bulb and the map light bulb are PC175.
The trunk or cargo area light uses 211-2.
The courtesy light bulb is 564, and it may be optional depending on the vehicle's equipment.
Because trim and lighting package differences can change fitment, and the same year CTS-V may have different bulb types in some positions. Checking the installed bulb helps confirm the correct size and avoids returns.
