The 2020 Mazda Mazda6 uses a mix of LED lighting and a few replaceable interior bulbs, so the best way to shop is by checking the bulb position on the vehicle. This page is designed to help you verify bulb sizes by lighting location, whether you are replacing an exterior lamp or an interior courtesy light.
For the 2020 Mazda6, many exterior functions are listed as LED, including the headlight high and low beam, brake lights, turn signals, parking lights, tail lights, daytime running lights, reverse lights, side markers, license plate lights, and the center high mount stop light. Interior and cargo-area bulbs are also shown here so you can match the correct fit before ordering.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm what is actually installed on your car before buying. Some 2020 Mazda6 models use LED assemblies that are not serviced with a simple bulb swap, while others may have replaceable interior bulbs such as DE3175, 194, or 7441. If you are considering an aftermarket LED conversion, check for compatibility with the housing, beam pattern, and any warning messages or flicker concerns. When in doubt, remove the old bulb and compare it to the replacement part before purchase.
