Additional Notes

The 7444NA is an ANSI-standard dual-filament wedge bulb in the T20 form factor, rated at 12V with a 21W main filament and a 5W secondary filament. The natural amber glass produces an amber output without the use of a painted or coated lens.
The 1034NA shares the same 12V, 21W/5W dual-filament electrical rating as the 7444NA but uses a BAY15d bayonet base rather than a wedge-style connector, making the two bulbs physically incompatible despite their identical wattage.
The 1034NA is a variant of the 1157, meaning it carries the same BAY15d base and general construction but is designated separately under ANSI standards for the North American market.
The Mazda CX-5 uses the 7444NA for the 2017-2023 model years and the 1034NA for the 2013-2016 model years, reflecting a base change between the two generations of the vehicle.
For the 2019-2020 Mazda CX-5, the 7444NA fitment is noted specifically for vehicles without LED tail lights, indicating that the parking light circuit on LED-equipped trims is served by a different arrangement.
The 2016 Mazda CX-5 specifies the 1034NA for vehicles with halogen capsule headlamps, indicating that trim-level or lighting package differences within that model year affect the correct bulb fitment.
Both the 7444NA and the 1034NA carry the "NA" suffix, which denotes natural amber glass. This suffix distinguishes them from clear-glass counterparts in the same bulb families, which would require a separate amber lens to produce a legal amber signal output.
Because the 7444NA uses a wedge base and the 1034NA uses a BAY15d bayonet base, the two bulbs cannot be substituted for one another regardless of their matching voltage and wattage ratings.
