Land Rover Range Rover Evoque Dome Light Bulb Size

Additional Notes

• The 12961 is a Philips part number designating a miniature wedge-style bulb in the T10 form factor, rated at 12 volts and 5 watts.
• The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 thirty-seconds of an inch, making it one of the smallest wedge bulbs used in automotive interior applications.
• The base type is W2.1x9.5d, a wedge base in which the glass envelope itself acts as the contact point, eliminating the need for a separate metal base or pins.
• At 5 watts, the 12961 operates at a low power draw, consistent with interior courtesy lighting roles such as dome and map light positions.
• The Land Rover Range Rover Evoque uses the 12961 bulb for its dome light across the 2015-2017 and 2021-2024 model years covered in these specifications.
• The W2.1x9.5d base is a specific wedge standard, and substituting a bulb with a different base type, such as a festoon or bayonet fitting, would result in an incompatible fitment regardless of voltage or wattage match.
• The T10 wedge format is widely shared across many vehicle makes and positions, which means aftermarket and LED replacement bulbs in this size are broadly available, though voltage and wattage ratings must still correspond to the 12V, 5W specification.
