Toyota Corolla Cross Turn Signal Bulb Size

Additional Notes

• The 7440NA is the front turn signal bulb for the Toyota Corolla Cross across the 2022-2024 model years.
• The 7440NA follows the ANSI standard, making it the designated specification for the United States and Canada markets.
• This bulb uses a single-filament wedge design in the T20 form factor, which is a common wedge base configuration used in automotive turn signal applications.
• The 7440NA operates at 12 volts with a 21-watt output, a wattage typical of incandescent turn signal bulbs intended to meet flash rate requirements set by automotive safety standards.
• The natural amber glass of the 7440NA produces its amber color through the glass itself rather than through a colored lens or coating, which is a defining characteristic of the "NA" designation in the bulb code.
• Because the amber tint is built into the glass, substituting a clear equivalent such as the standard 7440 would alter the color output of the turn signal and may not meet regulatory requirements for amber signal lighting.
