The Lexus NX200t uses 7440NA bulb size for both front and rear turn signal applications. The replacement chart covers 2015 to 2017 model year data and specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7440NA is the sole bulb type across all turn signal positions in the Lexus NX200t specifications covering model years 2015-2017.
The 7440NA is a single-filament wedge bulb built to the T20 form factor, rated at 12 volts and 21 watts.
The natural amber glass envelope of the 7440NA produces its amber output through the glass itself rather than through a clear bulb paired with an amber lens, which is a characteristic of the "NA" designation in the ANSI naming convention.
The 7440NA carries ANSI standardization applicable to the US and Canadian markets, meaning its physical and electrical characteristics conform to a defined North American specification.
On the Lexus NX200t, the front turn signal application of the 7440NA is conditional, applying only to vehicles equipped with halogen capsule headlamps across the 2015-2017 model years.
The rear turn signal position carries no such conditional notation, and the 7440NA applies to all 2015-2017 rear turn signal fitments without a stated trim or equipment restriction.
The T20 wedge base design means the bulb is retained by the socket through friction rather than a bayonet or screw mechanism, which is a relevant consideration for fitment and replacement.
A standard 7440 bulb uses a clear glass envelope, making it visually distinct from the 7440NA despite sharing the same base type and wattage. Substituting one for the other may affect the color output at the lens.
