Additional Notes

The 7440NA is the specified front turn signal bulb for the Lexus NX250 across the 2022-2024 model years.
The 7440NA follows the ANSI standard, making it the designated specification for the United States and Canadian markets.
This bulb uses a single-filament wedge base, classified under the T20 form factor, which is a common wedge-type base used in automotive signal lighting.
The natural amber glass of the 7440NA produces its amber output through the glass itself rather than through a clear bulb paired with an amber lens, a distinction relevant to fitment in housings designed for this configuration.
The 7440NA operates at 12 volts and draws 21 watts, which is the standard power rating for single-filament automotive turn signal bulbs in this class.
Because the 7440NA carries a specific amber glass designation, substituting it with a clear 7440 variant would alter the color output at the lens and may not meet signal lighting regulations in the applicable markets.
