The Toyota MR2 Spyder back up light uses bulb size 7440 for the rear lighting system. Provided information covers the specific time 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 7440 bulb is the sole bulb size specified across all listed model years of the Toyota MR2 Spyder for back up light applications, covering the 2000-2005 model year range in both the general and outer back up light positions.
The 7440 is a single-filament wedge bulb built to the T20 form factor, operating at 12 volts with a 21-watt output, and is recognized under ANSI standards in the United States and Canada.
The single-filament design of the 7440 distinguishes it from dual-filament bulbs in the same T20 family, such as the 7443, making those alternatives incompatible as direct replacements despite sharing the same wedge base style.
The outer back up light for the 2005 model year carries a production cutoff of January 2005, meaning vehicles built after that date fall outside the scope of this fitment entry.
The outer back up light for the 2000 model year specifies a production start date of December 1999, reflecting the early production timing of that model year rather than a calendar-year release.
