The Toyota Yaris parking light requires bulb size 7444NA or 7443NA depending on the specific configuration of the lighting assembly. Data for the lighting components covers the range from 2013 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7444NA and 7443NA are both ANSI-standardized dual-filament wedge bulbs in the T20 form factor, rated at 12V with a 21W/5W power split across their two filaments. The higher-wattage filament typically serves the primary lighting function, while the lower-wattage filament serves a secondary role such as parking or running light operation.
Both bulb types feature natural amber glass, which produces an amber-colored output without the use of a separate colored lens or coating. This construction is common in markets where amber front parking or turn signal light output is required by regulation.
The 7444NA and 7443NA share the same voltage rating, wattage configuration, T20 wedge base type, and natural amber glass construction, making their electrical and physical profiles nearly identical in most respects.
Despite their similarities, the 7444NA and 7443NA carry distinct ANSI part numbers, which indicates a difference in filament orientation or base contact configuration. Substituting one for the other without confirming socket compatibility may result in incorrect fitment or improper electrical contact.
The Toyota Yaris (2018) is specified with the 7444NA for the front parking light, while the 2013-2014 model years use the 7443NA, reflecting that the same vehicle nameplate has carried different bulb requirements across its production run.
The 2019 Toyota Yaris front parking light specification lists the 7444NA, consistent with the 2018 model year entry that also calls for the 7444NA.
