This page covers bulb sizes for the 2021 Mazda CX-5 and helps you verify the correct bulb by lighting position. Whether you are replacing an exterior signal, a cargo lamp, or an interior reading light, matching the bulb to the exact location is the safest way to avoid ordering the wrong part.

The 2021 CX-5 uses a mix of LED lighting and replaceable bulbs depending on the trim and lighting package. That means some positions are fixed LED assemblies, while others use serviceable bulbs such as 7444NA, 7440A, DE3175, 2825, 2825, 7443A, and 7443R on certain configurations.

Fitment can vary by market, trim level, and body style, so always compare the bulb chart with the lighting equipment already installed on your CX-5. Models with LED tail lights often use different rear lamp components than models without LED tail lights, and halogen-to-LED aftermarket conversions may require additional resistors or adapters to prevent warning lights or fast flashing. Before buying replacements, remove the old bulb and confirm the base type and socket shape, especially for turn signals, license plate lights, and interior DE3175 bulbs.
