The Toyota MR2 Spyder tail light requires a 7443 bulb size for proper installation and function within the rear lighting assembly. Data for the specific component covers the period from 2000 through 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7443 is the sole bulb type specified across all outer tail light positions for the Toyota MR2 Spyder, covering the 2000-2005 model years.
The 7443 is an ANSI-standard dual-filament wedge bulb in the T20 form factor, rated at 12 volts with a 21W/5W output, where the higher wattage filament serves braking or turn functions and the lower wattage filament serves running light functions.
As a dual-filament type, the 7443 cannot be directly substituted with a single-filament equivalent such as the 7440, as doing so would disable one of the two lighting functions the socket is designed to operate.
The 2000 model year outer tail light fitment carries a production date qualifier of "From 12/1999," indicating the specification applies only to vehicles produced from December 1999 onward within that model year.
The 2005 model year outer tail light fitment carries a production date qualifier of "To 01/2005," indicating the specification applies only to vehicles produced up to January 2005 within that model year.
The T20 wedge base of the 7443 is a push-in type that does not use a bayonet or screw fitting, which is a relevant factor when sourcing aftermarket or replacement units for the MR2 Spyder.
