Cadillac CTS-V 2013 Bulb Size
Bulb size chart
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.
