Additional Notes

The 12961 bulb, a Philips part number designation for a T10 miniature wedge bulb, is the most frequently specified trunk bulb across the Mitsubishi Outlander Sport lineup, appearing in model years 2011-2020 (with a body code qualifier for 2020) and 2013-2019 without restriction.
The T10 wedge bulb uses a W2.1x9.5d base, operates at 12 volts, and draws only 5 watts, placing it in the low-wattage category typical of interior and cargo area lighting applications.
The H11 is specified for the 2021-2022 Mitsubishi Outlander Sport trunk application, representing a distinct departure from the T10 wedge type used in earlier model years.
The H11 is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. Its wattage is eleven times higher than the 12961 it replaced in this application, making the two bulb types electrically and physically incompatible with each other.
The H11 carries ECE certification for use in Europe and worldwide markets and holds approval for use in the United States as well, reflecting its broad regulatory acceptance across regions.
The 2020 model year carries a manufacturer body code qualifier (GA5W) alongside the 12961 specification, indicating that fitment for that year is body-code-dependent rather than universal across all 2020 variants.
