For the 2007 Cadillac SRX, the high-beam headlight uses a 9005XS bulb. Low-beam fitment depends on the factory headlight system: models with halogen headlights use 9006XS, while models with HID headlights use D1S. Confirm the headlight type before ordering a low-beam replacement.
- Front turn signals use 3757A.
- Reverse lights use 3157.
- Brake, center stop, tail, and rear turn-signal lights are listed as LED.
- License plate and front side-marker lights may use 2825 or 98.
