This automotive maintenance tutorial was specifically written to assist owners of the 4th generation ND (2016, 2017, 2018, 2019, 2020 & 2021) Mazda MX-5 Miata in changing a burnt out license plate light bulb located in the rear bumper cover. Owners of other Mazda vehicles such as the Mazda2 (Demio), Mazda3 (Axela), Mazda5, Mazda6 (Atenza), CX-3, CX-5, CX-7, CX-9, RX-8 and MPV may also find these DIY instructions to be helpful. The compatible replacement miniature wedge base light bulb part number is 2825 (also known as W5W). If you would like to have brighter license plate lights, install some 2825 LED bulbs. The only tool needed to remove the light housing in order to access the sockets and replace the light bulbs is a small flathead screwdriver or a plastic pry bar tool. |
