Additional Notes

The Land Rover Discovery Sport (2021-2024, excluding 2022) uses the 12961 bulb for the dome light position.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts.
The T10 form factor is a small tubular bulb type widely used in low-current interior lighting applications across many vehicle makes.
The W2.1x9.5d base designation refers to a wedge-style base where the glass envelope itself acts as the retention mechanism, requiring no separate metal socket pins.
At 5 watts on a 12-volt circuit, the 12961 draws approximately 0.42 amperes, consistent with standard low-load interior lighting circuits.
The W2.1x9.5d base is a specific wedge standard, and substituting bulbs with physically similar but dimensionally different bases risks poor contact or fitment failure in the socket.
