Chevrolet Camaro Cornering Bulb Size

Additional Notes

• The Chevrolet Camaro uses the 7440 bulb for its cornering function across the 2021-2024 model years.
• The 7440 is a single-filament wedge bulb, meaning it serves one lighting function per socket rather than switching between two brightness levels.
• The T20 designation refers to the wedge base type of the 7440, which determines physical socket compatibility.
• The 7440 operates at 12 volts and draws 21 watts, which are standard ratings for automotive turn and cornering applications.
• The 7440 carries an ANSI standard classification recognized in both the United States and Canada.
• The 7440 and 7443 share the same T20 wedge base form factor but differ in filament count, making them physically similar yet functionally distinct. The 7443 is a dual-filament variant and is not a direct replacement for the single-filament 7440 in this application.
