Jaguar XF Glove Box Bulb Size

Additional Notes

• The Jaguar XF glove box uses the 12961 bulb across all listed model years from 2009 to 2024, with the exception of 2022, which does not appear in the specifications.
• 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 designation refers to a tubular bulb with a width of 10/8 of an inch, a form factor widely used in low-intensity interior lighting applications such as glove boxes, map lights, and courtesy lights.
• The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in its socket by the tension of the base itself rather than by a separate locking mechanism or bayonet pins.
• At 5 watts and 12 volts, the 12961 draws approximately 0.42 amperes, placing it in the low-current category typical of interior accent and compartment lighting.
• The consistent fitment of the 12961 across the 2009-2024 Jaguar XF means that a single bulb specification covers the full production range represented in these data, indicating no socket or voltage changes occurred across those years.
• The W2.1x9.5d base is not universally interchangeable with all T10-sized bulbs, as some T10 bulbs use different base configurations, and substitutions should match both the bulb type and base specification precisely.
