Additional Notes

The 7440 bulb is the sole back up light bulb size listed for the Mitsubishi i-MiEV across all model years in the specifications.
The 7440 follows the ANSI standard, meaning it conforms to a defined North American specification used in both the United States and Canada.
It is a single-filament bulb, which means it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as braking and running lights simultaneously.
The 7440 uses a T20 wedge base, a pin-free mounting style where the bulb is held in place by the shape of its plastic base pressing against the socket walls.
The bulb operates at 12 volts and draws 21 watts, values typical of standard incandescent automotive reverse lighting.
The i-MiEV years covered in the specifications are 2012, 2014, 2016, and 2017, all sharing the same 7440 fitment.
Because the 7440 is a single-filament T20 wedge type, it is not interchangeable with the 7443, which shares the same T20 wedge base but carries a dual-filament design and different wattage ratings.
