The 2014 Cadillac SRX can use two different headlight configurations depending on trim: halogen low beams use H11 bulbs, while HID-equipped models use HID bulbs for the low beam (with a separate high‑beam). The exact bulb designation varies by trim and production date.
Headlight configurations in the 2014 SRX
Two headlight setups were available for the 2014 SRX. The following outlines which bulbs correspond to each configuration.
- Halogen headlights (base and some trims): low beam typically uses H11; high beam uses 9005 (HB3).
- HID headlights (available on higher trims or as an option): low beam uses HID bulbs in a projector (bulb type varies by system; common GM options include D1S/D2S/D3S); high beam is usually a separate halogen bulb or an additional HID source depending on the assembly.
Note: Exact bulb types can vary by market and production date. Always verify by inspecting the bulb or checking the owner's manual or dealer data for your specific VIN.
How to confirm the exact bulb type for your vehicle
Use these steps to confirm the exact bulb designation for your 2014 SRX:
- Open the hood and locate the headlight assembly; remove the dust cap to view the bulb marking if safe to do so.
- Consult the owner’s manual or the section on replacing headlights for the exact bulb specification for your trim.
- If you have access to GM's parts database or a dealer, enter your VIN to pull the exact bulb part number for your vehicle.
- When in doubt, have a certified technician verify to ensure proper ballast compatibility for HID systems.
By confirming the bulb type, you avoid ordering the wrong replacement and ensure optimal beam pattern and color temperature.
Summary
In short: the 2014 SRX can take halogen bulbs (commonly H11 for low beam and 9005 for high beam) or HID bulbs for the low beam (with a separate high‑beam arrangement). The correct bulb depends on trim and production date; verify with the manual or VIN lookup, or share your trim and I can help identify the exact designation.
