This 2018 Mazda CX-5 bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Because Mazda used different lighting setups depending on trim, package, and market, it is important to confirm whether your CX-5 has LED or non-LED tail lamps and which exterior lamps are shared across versions.

For the 2018 Mazda CX-5, many key exterior lights are LED from the factory, including the headlight high beam and low beam, front fog light, daytime running light, reverse light, center high mount stop light, and several rear lamp functions on LED-equipped models. Other positions use replaceable bulbs such as 7444NA, 7440A, DE3175, 2825/98, and 7443A/7443R depending on the lamp location and equipment level.

Fitment can vary a lot on this model, especially between halogen-style and LED tail light versions, so always compare your installed bulb with the chart before ordering. If you are considering aftermarket LED conversions, make sure the bulb base, polarity, and housing depth are compatible, since some replacements may not work correctly in every reflector or projector housing. The safest approach is to check the bulb already in the vehicle, confirm the trim/package, and verify the exact lamp position before purchase.
