Ford Escape Door Mirror Illumination Light Bulb Size

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.
