2017–2025 Mazda CX-5 Headlight and Bulb Sizes

Which Mazda CX-5 model years does this cover?

These headlight bulbs specifications apply to every Mazda CX-5 built from 2017 through 2025 — the KF (2nd generation), compact suv. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2017–2025 Mazda CX-5

• 2017All-new KF generation on a stiffer platform; 2.0L dropped from the US lineup, 2.5L becomes the sole gas engine
• 2018Cylinder deactivation added to the 2.5L; g-Vectoring Control standard
• 20192.5L Turbo and 2.2L SkyActiv-D diesel both introduced (diesel on Signature trim only)
• 2020Diesel discontinued after this model year due to low take rate
• 2022Mid-cycle refresh: revised front/rear styling, wheel designs, and more standard driver-assist tech; mechanical specs carry over
• 2024Trim names simplified (2.5 S, 2.5 S Select, 2.5 S Preferred, 2.5 Turbo, etc.); final CX-5 model year before the 2026 all-new third generation

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.
