Additional Notes

The 7440NA is the sole front turn signal bulb type listed for the Lexus UX250h, appearing across all specified model years from 2019 to 2024.
The 7440NA is a single-filament wedge bulb built to the T20 form factor, operating at 12 volts and rated at 21 watts.
The natural amber glass of the 7440NA produces a yellow-orange output without relying on a colored lens or housing to filter a clear bulb, which is a characteristic of the NA designation in the ANSI naming convention.
The 7440NA conforms to ANSI standards recognized in both the United States and Canada, placing it within a standardized sizing and performance framework used across a wide range of North American vehicle applications.
The single-filament construction of the 7440NA means the bulb serves one lighting function only, as opposed to dual-filament types that handle two functions such as turn signaling and running light duties simultaneously.
For the 2019 model year, the 7440NA fitment is specified exclusively for vehicles equipped with LED headlamps, indicating that a trim or package distinction affects the correct front turn signal bulb for that year.
