Mitsubishi Mirage G4 front and rear side marker bulbs use a 12961 size replacement bulb. The chart covers 2017 to 2020 production years with corresponding bulb size specifications.
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 the 12961 bulb for both front and rear side markers across the 2017-2020 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The T10 designation refers to a tubular bulb approximately 10mm wide, commonly found in low-intensity automotive lighting positions such as side markers and courtesy lights.
The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism.
The 12961 operates at 12 volts and 5 watts, which is consistent with standard low-power automotive marker lighting.
The front and rear side marker positions on the Mirage G4 share the same bulb specification, meaning a single bulb type serves all four side marker sockets on the vehicle.
Because the front and rear positions use an identical bulb, a replacement purchased for one position is directly interchangeable with the other without modification.
