Fiat 500X Glove Box Bulb Size

Additional Notes

• The Fiat 500X uses the 12961 bulb for the glove box across all listed model years, spanning 2016-2023.
• 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.
• T10 bulbs are among the most widely used miniature bulbs in automotive interior applications, commonly appearing in glove boxes, map lights, and courtesy lighting positions.
• The W2.1x9.5d base type is the standard wedge base for T10 bulbs, where the bulb body itself acts as the contact point rather than a separate metal cap or pin configuration.
• At 5 watts, the 12961 draws minimal current, which is typical for interior courtesy lighting where the bulb may remain on for extended periods while a compartment is open.
• The W2.1x9.5d base designation is a standardized IEC specification, meaning bulbs from different manufacturers sharing this base type are generally interchangeable in terms of physical fitment, provided voltage and wattage ratings also match.
