For the 2010 Cadillac CTS-V, headlight fitment varies by the installed headlight system. The low-beam options are D1S and H11, while high-beam fitment includes D1S and H9. Confirm whether the vehicle uses the HID or halogen headlight configuration before ordering, since the correct bulb depends on the equipment installed.
The fog light uses an H11 LED bulb. Front turn-signal fitment also differs by headlight type: vehicles with halogen headlights use 2504 LED, while those with HID headlights use 12272NA.
Other useful replacement sizes include:
- 5201 for daytime running lights
- 2825 for license plate, parking, and dome lights
- 194NA for the front side marker
- 906 for glove-box and interior lighting
- PC175 for map lights
- 211-2 for the trunk light

No reverse-light bulb is listed in the supplied fitment data.
