Additional Notes

The 7440NA is the sole front turn signal bulb type listed for the Lexus UX200, appearing across the 2019 and 2021-2022 model years.
The 7440NA follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized automotive bulb.
As a single-filament wedge bulb in the T20 form factor, the 7440NA serves one dedicated electrical function rather than sharing a filament between multiple lighting roles such as braking and signaling.
The natural amber glass of the 7440NA produces its turn signal color through the bulb's own tinted envelope rather than relying on an amber-colored lens housing to filter a clear light source.
The 7440NA operates at 12 volts and 21 watts, which is consistent with standard 12-volt automotive electrical systems and a moderate wattage output typical of incandescent turn signal applications.
The 2019 UX200 front turn signal specification carries a "With LED Headlamps" qualifier, indicating that this bulb fitment applies specifically to that trim or package configuration for that year.
