Bulb size chart
This 2009 Cadillac CTS-V bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Whether you are replacing an exterior lamp or a small interior bulb, checking the exact socket location is the easiest way to avoid fitment mistakes.
The 2009 Cadillac CTS-V uses different bulb types depending on the lamp location and, in some cases, the headlight setup. This page organizes the common bulb sizes for the CTS-V by position, making it easier to find the right match for headlights, fog lights, markers, license plate lights, and cabin lighting.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb in your vehicle with the listing before ordering. Some CTS-V models use halogen lighting in certain positions, while others use HID components or LED-style replacements, and aftermarket conversions may change the required bulb type. If your car has been modified, or if you are unsure whether it has halogen or HID headlights, check the installed bulb or the existing housing before purchasing. Verifying the old bulb number and connector style is the safest way to confirm compatibility.
