Additional Notes

The 12961 is a Philips part number designating a miniature wedge bulb with a T10 form factor and W2.1x9.5d base, rated at 12V and 5W. This bulb is specified for the Hyundai Elantra GT across the 2013-2019 model years.
The 168 is an ANSI-standardized designation used in the United States and Canada, also a T10 miniature wedge bulb, rated at 12V and 4.9W. It is specified for the 2020 Hyundai Elantra GT.
Both the 168 and 12961 share the T10 wedge form factor and near-identical voltage ratings, though their wattage differs slightly at 4.9W and 5W respectively. Despite this physical similarity, they carry separate part designations under different standardization systems.
The W2.1x9.5d base notation on the 12961 describes a wedge-type base where 2.1 refers to the wire contact width in millimeters and 9.5 refers to the base length in millimeters. This base type is standard across T10 wedge bulbs, which is consistent with the 168 sharing the same form factor.
A change in bulb designation occurs between the 2019 and 2020 model years, shifting from the Philips 12961 to the ANSI 168. While both are T10 wedge bulbs, substituting one for the other without confirming socket and fitment compatibility is not advisable.
