Mitsubishi Mirage G4 headlight bulbs use 9003 and 9007 sizes for both high and low beam applications. The replacement bulb size chart covers 2017 through 2023 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Mirage G4 uses two distinct high beam and low beam bulb types across its model years: the 9003 for 2021-2023 and the 9007 for 2017-2020.
Both the 9003 and 9007 are dual-filament halogen bulbs, meaning a single bulb unit contains separate filaments for both high and low beam functions within the same housing.
The 9003 operates at 12 volts and carries a 60W filament for high beam and a 55W filament for low beam, while the 9007 operates at 12 volts with a 65W high beam filament and a 55W low beam filament.
Although both bulbs are dual-filament halogens operating at 12 volts, the 9003 and 9007 are not interchangeable. They use different base types: the 9003 has a P43t base and the 9007 has a PX29t base.
The differing base configurations between the 9003 and 9007 mean that a bulb from the 2017-2020 model years will not physically fit the headlight housing of a 2021-2023 Mirage G4, and vice versa.
Both the 9003 and 9007 are classified under ANSI standards and are recognized specifications in the United States and Canada.
The higher wattage on the 9007 high beam filament (65W versus the 9003's 60W) reflects a greater power draw for that function, though both share the same 55W rating on their low beam filaments.
