The Mitsubishi Mirage brake light uses P21/5W, 2057, and 1157 bulb sizes depending on the specific production period for the vehicle. Available information covers the time range from 1985 through 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 2057 bulb is the most widely used brake bulb type across the Mitsubishi Mirage's brake light specifications, appearing in the majority of model years covered.
Both the 1157 and 2057 are dual-filament bulbs sharing the BAY15d bayonet base and 12V operation. The 2057 draws 26.9W on its high filament compared to 21W for the 1157, making the 2057 the higher-wattage variant of the two.
Because the 1157 and 2057 share the same BAY15d bayonet base, they are physically interchangeable in terms of socket fit, though their wattage outputs differ.
The Mitsubishi Mirage uses the 2057 bulb for brake lights across the 1989-1991 and 1993-2002 model years, while the 1157 is specified for 1985-1988, 1992, 2014, and 2015.
The 1992 model year is a notable exception within the 1989-2002 period, as it uses the 1157 rather than the 2057 specified for the surrounding years.
For the Center High Mount Stop Light, the Mitsubishi Mirage uses two distinct single-filament bulb types: the 1156 with a BA15s bayonet base and the 921, which is a T15 wedge-base bulb.
The 1156 and 921 are not interchangeable. The 1156 uses a BA15s bayonet base, while the 921 uses a wedge-style base, meaning socket compatibility differs between the two.
The Center High Mount Stop Light on the 2001 Mirage uses the 921 wedge bulb, while the 2000 and 2002 model years use the 1156 bayonet bulb, indicating a socket change between certain production years.
The 921 is rated at 16W, making it the lowest-wattage bulb among all four types listed in these specifications.
All four bulb types listed, the 1157, 2057, 1156, and 921, conform to ANSI standards applicable in the United States and Canada, and all operate at 12V.
