# 2017-2025 Mazda CX-5 Headlight and Bulb Sizes

Headlight bulb types vary by trim on the 2017-2025 Mazda CX-5. Full bulb chart for every position, plus whether LED replacements fit the factory housings.

## 2017-2025 Mazda CX-5 bulb chart

| Position | Bulb type |
| --- | --- |
| Low beam | H11 (Sport/Touring, gas 2.5L, 2017-2021); LED sealed projector standard on Grand Touring/Signature from launch and across more trims after the 2022 facelift |
| High beam | 9005 (HB3) on halogen trims; LED module on LED-equipped trims |
| note | Where LED headlamps are fitted the unit is a sealed module, a failure means an assembly or dealer-level repair, not a bulb swap. Confirm trim/year before ordering. |

Note: Bulb fitments can vary with option packages (halogen vs. LED lighting). Confirm the bulb you are removing matches before ordering.

## 2017-2025 Mazda CX-5 headlight bulbs: common questions

### What headlight bulb does a 2017-2025 Mazda CX-5 use?

H11 (Sport/Touring, gas 2.5L, 2017-2021); LED sealed projector standard on Grand Touring/Signature from launch and across more trims after the 2022 facelift for the low beam and 9005 (HB3) on halogen trims; LED module on LED-equipped trims for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

### Can you put LED bulbs in a 2017-2025 Mazda CX-5?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
