Additional Notes

The Toyota GR86 uses two T10 miniature wedge bulbs for its courtesy lighting across the 2022-2024 model years: the 12961 and the 168.
The T10 form factor is a small cylindrical glass envelope commonly used in interior and courtesy lighting applications across the automotive industry.
The 12961 is a Philips part number designation for a T10 wedge bulb rated at 12V and 5W, fitted with a W2.1x9.5d base, and it applies to the 2023-2024 GR86.
The W2.1x9.5d base is a standardized wedge-type connector in which the glass envelope itself acts as the contact point, requiring no separate metal base pins.
The 168 is an ANSI-standard designation recognized in the United States and Canada, covering a T10 wedge bulb rated at 12V and 4.9W, and it applies to the 2022 GR86 produced from October 2021 onward.
Although both the 12961 and the 168 share the T10 wedge form factor and nearly identical wattage ratings, they carry different part number systems and a 0.1W power difference, which may be relevant for precise OEM replacement.
The mid-year production cutoff noted for the 2022 model, specified as from October 2021, indicates that the 168 fitment is tied to a specific production window rather than the full model year.
