This 2010 Cadillac CTS-V bulb size page is designed to help you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing a headlight, a marker lamp, or an interior bulb, matching the bulb to the exact location is the safest way to avoid fitment mistakes.
The 2010 Cadillac CTS-V could use different lighting setups depending on trim, market, and body style, so the bulb chart below is organized by function rather than by a single one-size-fits-all list. That makes it easier to compare your car’s installed bulbs with the correct replacement type for each lamp position.
For best results, confirm your vehicle’s headlight package before ordering. Some 2010 CTS-V models use halogen-style bulbs in certain positions, while others with HID headlights use different parts for the same front lighting functions. LED replacements and aftermarket conversions can also change fitment, beam pattern, or connector needs, so it is smart to compare the installed bulb and housing before purchase. If your car has been modified, always check the actual bulb in the vehicle rather than relying only on trim level or previous owner information.
The listed low beam headlight bulb is H11 for the 2010 Cadillac CTS-V. Always confirm whether your car has the standard setup or a different lighting package before ordering.
The high beam headlight bulb listed for the 2010 Cadillac CTS-V is H9. This applies to the standard bulb chart entry for that lighting position.
Yes. For versions with HID headlights, the chart lists D1S for the headlight bulb high beam and low beam position. That is different from the H11 and H9 setup used on other configurations.
The front fog light bulb is listed as H11 LED. If your vehicle has been converted or modified, make sure the LED replacement is compatible with the housing and connector.
The daytime running light bulb listed for the 2010 Cadillac CTS-V is 5201. Check the lamp function carefully, since daytime running lights can be confused with parking lights on some vehicles.
The front turn signal bulb depends on headlight type. Models with HID headlights use 12272NA, while models with halogen headlights use 2504 LED. Be sure to match the correct version to your headlight setup.
The license plate light bulb listed for the 2010 Cadillac CTS-V is 2825. The same bulb number is also shown for the parking light and dome light positions on this page.
Both the parking light bulb and dome light bulb are listed as 2825 for this model year. It is still a good idea to verify the installed bulb before buying, especially if the car has been altered.
The glove box light bulb and interior door light bulb are both listed as 906. These small interior bulbs can vary if the vehicle has been modified or if a previous owner installed a different type.
The stepwell light bulb listed for the 2010 Cadillac CTS-V is 2886X. If the light output looks different from stock, check whether an aftermarket bulb was installed.
The front side marker light bulb is listed as 194NA. This is a common exterior marker bulb, but the exact fit should still be confirmed against the installed part.
The vanity mirror light bulb listed for this vehicle is 6612F. These bulbs are small and easy to replace once you confirm the correct size.
The trunk or cargo area light bulb is listed as 211-2. If your trunk lamp has been changed to LED or a different socket style, compare the old bulb before ordering.
The map light bulb listed for the 2010 Cadillac CTS-V is PC175. Because interior lighting can vary by package, checking the existing bulb is recommended.
Because trim, lighting package, market, and body style can change the bulb used in a given position. Checking the installed bulb helps prevent ordering the wrong part, especially on a 2010 Cadillac CTS-V with HID headlights or aftermarket lighting changes.
