The 2008 Cadillac SRX uses different bulb types depending on the lighting position and equipment package. Some models may have HID low beams while others use halogen, and rear or interior lighting can also vary by trim or market.

Headlight fitment can differ between HID and halogen setups, and aftermarket LED conversions may require additional parts or may not match the original beam pattern. Even when the listed bulb size is correct, it is smart to check the old bulb, connector style, and housing design first so you avoid buying the wrong part.
