Additional Notes

The Mazda CX-5 luggage compartment uses two bulb sizes across its model years: the DE3175 and the DE3022, both of which are ANSI-standard festoon bulbs rated at 12V with a 31mm length and end-cap contacts.
Both the DE3175 and DE3022 are festoon-type bulbs, meaning they are cylindrical in form and make electrical contact through metal caps at each end rather than through a base socket.
The DE3175 is the luggage compartment bulb size for the Mazda CX-5 across the 2019-2023 model years, as well as the 2016 model year.
The DE3022 is the specified luggage compartment bulb size for the 2013-2015 model years.
Although the DE3175 and DE3022 share the same 31mm length, voltage rating, and contact style, they are listed as distinct part numbers and are not confirmed as interchangeable within these specifications.
The 2020 Mazda CX-5 carries a conditional fitment note: the DE3175 applies only to vehicles without LED tail lights, indicating that trim or package level affects the applicable bulb specification for that model year.
