Hyundai Azera Stepwell Bulb Size

Additional Notes

• The Hyundai Azera stepwell position uses the 12961 bulb across the 2009-2017 model years covered in these specifications.
• 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 designation refers to the bulb's tubular shape, with the W2.1x9.5d base describing a wedge-style base that requires no locking mechanism, relying instead on socket tension to hold the bulb in place.
• The 2017 model year specification carries a production cutoff of December 8, 2016, meaning vehicles assembled after that date fall outside the scope of this fitment entry.
• The 2015 model year specification applies from October 2, 2014, indicating a mid-cycle production change that defines when this fitment became applicable.
• The 2010 and 2009 model year entries both share a start date of December 15, 2009, which places both within the same production window for this bulb fitment.
• The W2.1x9.5d base type is not universally interchangeable with all T10 wedge sockets, as base width tolerances can vary between socket designs, making exact base specification relevant to fitment.
