Cadillac CTS-V 2010 Bulb Size
Bulb size chart
This 2010 Cadillac CTS-V bulb size page is designed to help you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing a headlight, a marker lamp, or an interior bulb, matching the bulb to the exact location is the safest way to avoid fitment mistakes.
The 2010 Cadillac CTS-V could use different lighting setups depending on trim, market, and body style, so the bulb chart below is organized by function rather than by a single one-size-fits-all list. That makes it easier to compare your car’s installed bulbs with the correct replacement type for each lamp position.
For best results, confirm your vehicle’s headlight package before ordering. Some 2010 CTS-V models use halogen-style bulbs in certain positions, while others with HID headlights use different parts for the same front lighting functions. LED replacements and aftermarket conversions can also change fitment, beam pattern, or connector needs, so it is smart to compare the installed bulb and housing before purchase. If your car has been modified, always check the actual bulb in the vehicle rather than relying only on trim level or previous owner information.
