Additional Notes

The Hyundai Santa Fe glove box uses two distinct bulb types across its production years: the 12961, a miniature wedge bulb, and the DE3423, a festoon-style bulb. These two types are not interchangeable due to their fundamentally different base designs and physical configurations.
The 12961 is a Philips part number designation for a T10 wedge bulb. It uses a W2.1x9.5d base, operates at 12V, and draws 5W. The wedge base relies on the bulb's glass envelope being pinched at the bottom to form the electrical contacts, which seat directly into a matching socket.
The DE3423 is an ANSI-standardized festoon bulb recognized across the United States and Canada. It measures 41mm in length and makes electrical contact through metal end caps at each tip rather than through a base socket. Its wattage is not specified in the available data, though it operates at 12V.
The Hyundai Santa Fe (2002-2006) uses the DE3423 festoon bulb for the glove box. The 2021 and 2023 model years use the 12961 wedge bulb instead, reflecting a change in socket type between these production periods.
The 2002 specification carries a production date qualifier of "From 2/1/2002," and the 2006 specification is limited to vehicles produced "To 2/15/2006." These date restrictions indicate mid-year production changes within those model years, meaning not all 2002 or 2006 Santa Fe vehicles necessarily share the same glove box bulb fitment.
The 2022 model year does not appear in the specifications, while 2021 and 2023 both list the 12961. Each year's fitment should be treated independently rather than assumed to follow a continuous pattern.
The T10 designation on the 12961 refers to the bulb's tubular shape, with the number indicating a width of 10 eighths of an inch. This is a widely used size in automotive interior lighting applications, and compatible replacements from other manufacturers are available provided they share the W2.1x9.5d base specification.
Festoon bulbs such as the DE3423 are held in place by spring-loaded clips within the lamp housing rather than by a socket. Substituting a wedge-type bulb in a festoon housing, or vice versa, would result in an improper fit regardless of voltage or wattage compatibility.
