Additional Notes

The Hyundai Tucson license plate bulb specifications cover three distinct bulb types across the 2005-2024 model range: the 12961, the 168, and the DE3423.
The 168 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, and it fits the Hyundai Tucson (2010-2020).
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, and it applies to the 2021-2024 Tucson.
Although both the 168 and the 12961 share the T10 wedge form factor, the 12961 carries a manufacturer-specific part number rather than an ANSI designation, and its wattage of 5W differs slightly from the 168's 4.9W rating.
The DE3423 is an ANSI-standard festoon bulb with a 41mm length and end-cap contacts, operating at 12V, and it is specified for the 2005-2009 Tucson.
Festoon bulbs such as the DE3423 use a cylindrical body with metal contacts at each end, a design that is physically incompatible with the wedge-base socket used by the T10 bulbs specified for later model years.
The W2.1x9.5d base designation on the 12961 refers to a specific wedge-base standard defined by the IEC, indicating a 2.1mm wire width and a 9.5mm insertion depth.
Because the DE3423 festoon type and the T10 wedge type require different socket configurations, bulbs from one group are not interchangeable with those from the other.
