Lexus UX250h Turn Signal Bulb Size

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.
