The Toyota Matrix tail light utilizes a 7443 bulb size for illumination across all listed vehicle applications. Data provided for the specific component covers the range from 2003 to 2013.
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 outer tail light bulb type specified for the Toyota Matrix across the 2003-2013 model years.
The 7443 is an ANSI-standard dual-filament wedge bulb classified under the T20 form factor, operating at 12 volts with a wattage rating of 21W for the primary filament and 5W for the secondary filament.
The dual-filament design of the 7443 allows a single bulb to serve two lighting functions simultaneously, typically combining stop or turn signal operation with a lower-intensity running or parking light function.
The T20 wedge base of the 7443 is a push-in connector type that does not use a separate metal base, which distinguishes it from bayonet-style automotive bulbs.
A production cutoff notation of "To 08/2013" is recorded for one fitment entry in the 2013 model year, indicating that a specific vehicle configuration produced up to that date corresponds to that entry.
A similar production cutoff notation of "To 01/2008" is recorded for one fitment entry in the 2008 model year, indicating a mid-year specification boundary for that configuration.
The 7443 and 7440 share the same T20 wedge base, but the 7440 is a single-filament bulb. Substituting a 7440 for a 7443 in a dual-filament application would result in the loss of one lighting function.
