Additional Notes

The DE3423 is an ANSI-standardized festoon bulb with a 41mm length and end-cap contacts, operating at 12V. Festoon bulbs make contact at both ends of the housing rather than through a base socket, which is a defining characteristic of the festoon form factor.
The Hyundai Sonata uses the DE3423 for its glove box across the 1999-2005 and 2017 model years, making it the most frequently specified bulb type in these glove box fitment records.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base pins.
The 2016 Hyundai Sonata specifies the 12961 wedge bulb for the glove box, which is a different bulb type and base style than the DE3423 festoon used in the 2017 model year. These two bulbs are not interchangeable due to their different contact configurations.
The 1891 is an ANSI-standardized T5 miniature wedge bulb rated at 12V and 2W. At 2W, it draws less power than the 12961, which is rated at 5W.
The 1989-1994 Sonata model years specify the 1891 bulb for the glove box. The T5 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, placing it among the smaller miniature wedge bulb sizes.
All three bulb types specified across these records operate at 12V, consistent with standard automotive electrical systems. However, their base types differ across all three, meaning none of the three bulbs is a drop-in substitute for another.
