Cadillac CTS-V 2006 Bulb Size
Bulb size chart
This 2006 Cadillac CTS-V bulb size page helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Because the CTS-V could be equipped with different lighting setups, checking the bulb chart by location is the safest way to confirm fitment for headlights, exterior lamps, and interior lights.
Use this guide to find the bulb type for each lamp on your 2006 Cadillac CTS-V, including the low beam, high beam, brake light, tail light, license plate light, turn signals, and cabin bulbs. It is designed to make replacement easier whether you are repairing a burned-out bulb or planning a lighting upgrade.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb listed here with the one already installed in your vehicle. The 2006 CTS-V may use different low beam setups depending on whether it has HID headlights or halogen headlights, and aftermarket LED conversions can change the bulb type or require extra adapters, resistors, or housings. Before ordering, remove the old bulb and check the base style and markings to avoid a mismatch, especially for exterior lights that may look similar but use different part numbers.
