Data for US-market versions with halogen headlights. Positions not listed are ones we couldn’t confirm: check your owner’s manual or the old bulb.
How to check which bulb your car takes
The Mazda CX-5 KF was built from 2017–2024. If your car is from those years, the bulbs in the chart are for US-market versions with halogen headlights. Before you buy, double-check one of these three ways:
- Owner’s manual: the maintenance or “bulb replacement” section has the official chart with every bulb.
- The old bulb: the size (9005, H11, 194…) is stamped on the metal base or the plastic housing.
- The headlight: many headlight assemblies have a label on the back listing the bulb for each light.
Watch out for refreshes: some models change headlights mid-generation. If your car is from a changeover year, check the old bulb.
Still not sure? Our guide on how to find out which bulb your car takes covers the other methods and the most common pitfalls, and the complete car bulb guide brings everything together.
Can you put LED bulbs in the Mazda CX-5 KF?
For the low and high beams, LED retrofit bulbs installed in a headlight housing designed for halogen bulbs are not DOT / FMVSS 108 compliant for on-road use in the US, even when the packaging says “DOT approved”. A halogen reflector or projector isn’t built for an LED light source, so the beam pattern can scatter and glare oncoming drivers, and it may cause dashboard warnings or problems at a state inspection. We explain the rules in more depth in our guide on whether LED headlight bulbs are street legal.
If you want more light without the hassle, high-performance halogen bulbs (up to +100% to +200% brighter) are street legal and fit any headlight.

Frequently asked questions
Should I replace headlight bulbs in pairs?
Yes, it’s recommended. Both low beam bulbs get the same use, so if one burns out the other won’t last much longer. Replacing them together keeps one headlight from being brighter than the other and restores the original light output.
Is it legal to put LED headlight bulbs in the Mazda CX-5 KF?
Not in the headlights, if they were designed for halogen bulbs: LED retrofit bulbs in halogen housings are not DOT / FMVSS 108 compliant for on-road use. LED bulbs are common and fine for turn signals, parking, license plate and dome lights, as long as they keep the right color.
