This 2013 Cadillac CTS-V bulb size guide helps you verify the correct replacement bulb by lighting position, so you can shop with more confidence. Whether you are changing a headlight, a parking light, or a small interior lamp, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The CTS-V could be equipped with different lighting setups depending on market, trim, body style, and package content. Use the bulb chart on this page to compare each position before ordering, especially if your car has HID headlights, halogen headlights, or an upgraded lighting package.
For best results, confirm the bulb already installed in your vehicle before buying replacements, since trim and package differences can change the correct fitment. This is especially important when comparing halogen versus LED applications, or when the car has been modified with aftermarket lighting conversions. Some owners replace factory bulbs with LED alternatives, but the base bulb size still needs to match the socket and housing. If your CTS-V has been altered, or if the previous owner installed non-original parts, checking the old bulb and the connector style can save time and prevent returns.
The low beam headlight bulb listed for this page is H11. Always verify the headlamp type on your car before ordering, since lighting equipment can vary by market and setup.
The high beam headlight bulb listed here is H9. If your vehicle has a different lighting package or has been converted, confirm the installed bulb before purchase.
Yes. For vehicles with HID headlights, the chart lists D1S for the high beam and low beam headlight bulb position. This is different from the H11 and H9 setup used on other configurations.
The front fog light bulb listed is H11 LED. If your fog lights have been modified, make sure the replacement matches both the bulb size and the connector style.
The daytime running light bulb listed for this model year is 5201. Check the existing bulb and housing before ordering, especially if the car has aftermarket lighting.
For CTS-V models with halogen headlights, the front turn signal bulb listed is 2504 LED. This fitment is specific to that lighting setup.
For CTS-V models with HID headlights, the front turn signal bulb listed is 12272NA. This is different from the halogen-headlight version, so headlight type matters.
The license plate light bulb listed is 2825. This same bulb size is also shown for the parking light and dome light positions on this page.
Both the dome light bulb and the parking light bulb are listed as 2825. It is still a good idea to confirm the installed bulb if your CTS-V has been changed or repaired before.
The glove box light bulb is 906, the interior door light bulb is 906, and the stepwell light bulb is 2886X. These small interior bulbs can vary with trim and equipment, so checking the original bulb is smart.
The vanity mirror light bulb listed is 6612F. If one side is out, compare the working side before replacing both bulbs.
The trunk or cargo area light bulb listed is 211-2. This is a common small interior bulb, but the exact socket and lens style should still be checked on the vehicle.
The map light bulb listed is PC175. If your overhead console has been modified or repaired, confirm the bulb in the housing before ordering.
Yes. Trim, lighting package, market, and body style can all affect bulb fitment. That is why this page organizes bulbs by lighting position and why checking the installed bulb is recommended before buying.
