For the 2015 Cadillac SRX, headlight fitment varies by the installed lighting system. The low beam uses either D2S or H11, while the high beam uses either D2S or 9005. Verify the bulb and headlight type before ordering, since these options are not interchangeable.
Daytime running light and parking light fitment also depends on the headlights. SRX models with halogen headlights use H11 LED or H16 LED for the daytime running light and 7444NA for the parking light. Models with HID headlights use 7443 for both applications.
- Front turn signal: 7444NA or 2827; compare the original bulb when an option is listed.
- Rear turn signal: 7440.
- Reverse light: 5008.
- Brake, tail, center stop, and rear side-marker lights are LED.
- License plate and dome/map lights use 2825 or 98.
