Mitsubishi Mirage Turn Signal Bulb Size

Additional Notes

• The 1156NA bulb is the most frequently specified type across the Mitsubishi Mirage turn signal positions. It is an ANSI-standard single-filament bulb with a BA15s bayonet base, natural amber glass, rated at 12V and 21W.
• The standard 1156 bulb shares the same BA15s bayonet base and 12V/21W electrical rating as the 1156NA. The sole distinction is that the 1156NA incorporates natural amber glass, while the 1156 uses clear glass.
• Because the 1156 and 1156NA share the same base type and wattage, physical fitment is compatible between the two. However, substituting a clear 1156 for an 1156NA in a position that relies on the bulb's amber glass for color output will affect the signal color.
• The front turn signal of the Mitsubishi Mirage uses 1156 for model years 2023-2024, while 2017-2022 (excluding 2020 and 2023) and earlier modern-era years use 1156NA, indicating a shift away from the amber-glass variant in the most recent entries.
• The rear turn signal for the Mitsubishi Mirage (2018-2024) specifies the PY21W, an ECE-standard single-filament amber bulb with a BAU15s bayonet base rated at 12V and 21W. The BAU15s base is offset and is not interchangeable with the BA15s base used by the 1156 and 1156NA.
• The 2017 rear turn signal specifies the 12496, a Philips/Osram part number for a specialty halogen application at 12V, which differs from both the PY21W used in surrounding years and the 1156 used in earlier model years.
• The 1157 is a dual-filament bulb with a BAY15d bayonet base rated at 12V and 21W/5W. It appears in the front turn signal position for the Mirage across 1985-1988 and 1993-1996, as well as in the 1988 model year.
• The 1034NA, specified for the 2002 front turn signal, is an amber-glass dual-filament variant of the 1157 with a BAY15d base rated at 12V and 21/5W. Its dual-filament design distinguishes it from the single-filament 1156NA used in other front turn signal years.
• The front outer turn signal on the Mitsubishi Mirage for 2019-2020 uses the 12961, a Philips miniature wedge bulb with a W2.1x9.5d base rated at 12V and 5W. This is a significantly lower wattage than all other turn signal bulbs in these specifications and uses an entirely different base type.
• The 2019-2020 Mirage front turn signal system is split across two separate positions, with the inner position using the 1156NA and the outer position using the 12961. These two bulbs have incompatible bases and different wattage ratings, making them non-interchangeable with each other.
