Additional Notes

The 12961 is the sole bulb size listed across all three model years of the Ford Escape covered in these specifications, making it the defining bulb for this application.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 bulb uses a W2.1x9.5d base, which is a wedge-style base that relies on friction fit rather than a locking twist mechanism for retention.
The 2019-2020 entries explicitly label this bulb's function as a puddle light, which is a downward-facing lamp housed in the door mirror that illuminates the ground beside the vehicle.
The W2.1x9.5d base designation is standardized, meaning 12961-type bulbs from different manufacturers sharing this base type are generally interchangeable at the socket level, provided voltage and wattage ratings also match.
At 5 watts on a 12-volt circuit, the 12961 draws approximately 0.42 amperes, which is consistent with low-current auxiliary lighting circuits typical of puddle light applications.
The Ford Escape (2018-2020) uses the same 12961 bulb specification across all three years covered, indicating no change in the mirror illumination hardware during this period.
