The low-beam bulb in Mazda CX-5 models with halogen headlights is typically an H11 bulb; LED headlights use a non-replaceable LED module, and HID setups use xenon bulbs with ballast (exact bulb type varies by year and market).
Because the CX-5 has evolved across generations (2012–2016, 2017–2021, and the 2022 refresh) and across trims, the light source can differ. Check your owner's manual or inspect the headlight assembly to confirm whether you have halogen, LED, or HID lighting before buying a replacement.
Headlight configurations and what they mean for bulb replacement
Before listing the common scenarios, note that the exact bulb type depends on year, trim, and whether the vehicle uses traditional halogen, LED, or HID headlights. The following categories cover the most frequent setups you’ll encounter.
- Halogen low beams: The vast majority of CX-5s with halogen headlights use H11 bulbs for the low beam.
- LED headlights: On higher trims or newer models, CX-5 may come with LED headlights. In this case, there is no replaceable low-beam bulb; the light source is an integrated LED module.
- HID (xenon) headlights: Some trims/years used HID low beams. These systems use a ballast and a xenon bulb; replacement specifics can vary by year and market, and some models require servicing the entire headlight unit.
When in doubt, consult the owner’s manual or contact a Mazda dealer to confirm the exact bulb type for your vehicle’s year and trim, and to learn the recommended replacement procedure.
How to identify your CX-5 headlight type
Here are quick ways to determine what kind of low-beam system you have without removing the bulb:
- Check the owner’s manual or the information placard in the driver’s door jamb for headlamp specifications.
- Inspect the headlight housing: a visible LED array indicates LED headlights; a standard bulb with a socket and wiring suggests halogen or HID (with ballast).
- Look for a ballast or high-voltage wiring near the headlight assembly, which signals HID; absence of ballast often indicates halogen.
Always use proper safety precautions when working around electrical components, and ensure the vehicle is off and cool before handling bulbs.
Summary
For most CX-5 models with halogen headlights, the low-beam bulb is an H11. If your CX-5 uses LED headlights, there is no replaceable bulb; if it uses HID headlights, the system relies on a ballast and xenon bulb with year-specific variations. Verify the exact setup for your vehicle with the owner's manual or a Mazda dealer to ensure you purchase the correct replacement.
