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.
The 2006 Cadillac CTS-V uses a D1S bulb for low beam if it has HID headlights. If the car has halogen headlights, the low beam bulb is 9006XS. Check which headlight setup is installed before buying replacements.
The high beam bulb is 9005XS. This applies to the 2006 Cadillac CTS-V high beam position listed on the bulb chart.
The front fog light bulb listed for this vehicle is 9145 LED. If you are replacing a fog light, confirm the lamp housing and connector before choosing an LED replacement.
The daytime running light bulb is 3157. This is the bulb size shown for the 2006 Cadillac CTS-V DRL position.
Both the brake light bulb and tail light bulb are listed as 3157R. That means the same bulb type is used in those rear lighting positions on this model.
The rear turn signal light bulb is 3157A. Make sure you match the rear signal position specifically, since the front signal bulb can be different.
The front outer turn signal light bulb is 2825. This is separate from the front inner turn signal listing, so check the exact lamp location before ordering.
The front inner turn signal light bulb is 3157A. It is different from the front outer turn signal bulb, which is listed as 2825.
The license plate light bulb is 2825. This same bulb size is also listed for the parking light and the rear side marker light on this page.
The parking light bulb is 2825. If you are replacing the front parking lamps, confirm the socket and lens style before installing the new bulb.
The front side marker light bulb is 194NA. This is a different bulb from the rear side marker light, so do not assume both ends use the same part.
The rear side marker light bulb is 2825. That differs from the front side marker bulb, which is 194NA.
The back-up reverse light bulb is 3157. If one reverse light is out, it is usually a good idea to replace both sides at the same time.
The trunk or cargo area light uses a 211-2 bulb. This is an interior utility bulb, so handle it carefully to avoid breaking the glass or damaging the socket.
The dome light bulb, map light bulb, and center high mount stop light bulb are all listed as PC175. Check the specific lamp housing before purchase, since interior fixtures can vary with equipment and market.
The courtesy light bulb is 564, and it may be optional depending on the vehicle’s equipment. If your CTS-V does not have a courtesy lamp in that location, you may not need this bulb.
