This 2012 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 location first is the easiest way to avoid ordering the wrong fit.
The 2012 Cadillac CTS-V can use different bulb types depending on trim, lighting package, body style, and headlight setup. Use the chart on this page to compare each position, including low beam, high beam, fog lights, parking lights, and cabin lighting, before starting your replacement.
Fitment can vary on the 2012 Cadillac CTS-V, especially between halogen and HID-equipped cars, and between markets or body styles. Some positions may also have LED or aftermarket conversion options, which can change the bulb type or the way the lamp is serviced. Before purchasing, check the bulb currently installed in your vehicle and compare it with the listing for that exact lighting position. If your car has been modified with LED upgrades, projector swaps, or nonfactory housings, the original bulb size on the chart may not match what is installed now.
The low beam bulb listed for the 2012 Cadillac CTS-V is H11. Always confirm your headlight type before ordering, since some lighting setups can differ by package or market.
The high beam bulb listed is H9. If your CTS-V has a different headlight configuration, check the installed bulb and compare it to the chart before replacing it.
Yes. For HID-equipped headlights, the chart lists D1S for the high beam and low beam setup. This is different from the halogen-style H11 and H9 listings, so headlight type matters.
The front fog light bulb is listed as H11 LED. If your vehicle has been converted or modified, verify the actual lamp and connector before buying a replacement.
The daytime running light bulb listed for this model is 5201. It is a separate fitment from the headlight bulbs, so do not assume the DRL uses the same bulb as the low beam or high beam.
The front turn signal bulb depends on the headlight setup. With HID headlights, the listing is 12272NA. With halogen headlights, the listing is 2504 LED. Check which headlight system your car has before ordering.
The license plate light bulb is listed as 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 parking light bulb are listed as 2825 for the 2012 Cadillac CTS-V. Even when the same bulb size appears in multiple places, it is still best to confirm the location before replacement.
The chart lists 906 for the glove box light and interior door light, 2886X for the stepwell light, 6612F for the vanity mirror light, and PC175 for the map light. These small interior bulbs can vary by trim and equipment level.
The trunk or cargo area light bulb is listed as 211-2. If your car has cargo lighting changes from an aftermarket upgrade, check the installed bulb to make sure the replacement matches.
The front side marker light bulb is listed as 194NA. However, lighting package differences can affect the exact fitment, so it is smart to compare the old bulb and the chart before purchasing.
Because the 2012 Cadillac CTS-V can vary by trim, body style, and lighting package, the installed bulb is the best confirmation of fitment. This is especially important for headlight, fog light, and turn signal positions, where halogen, HID, and LED setups may not use the same part.
