Additional Notes

The 168 bulb is an ANSI-standard miniature wedge type in the T10 form factor, rated at 12V and 4.9W. It is the most frequently specified bulb across both the front and rear side marker positions in the Hyundai Elantra GT specifications.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. Although it shares the T10 form factor with the 168, it carries a manufacturer-specific part number rather than an ANSI designation.
Both the 168 and 12961 use the T10 wedge form factor, meaning their physical housing is the same general type. However, the 12961 specifies a W2.1x9.5d base, and the two bulbs differ slightly in wattage, at 4.9W and 5W respectively.
The front side marker position on the Hyundai Elantra GT (2018-2019) calls for the 12961 specifically under the condition of halogen capsule headlamps, while the 2020 model year with the same headlamp configuration returns to the 168.
For model years 2013-2017, the front side marker position specifies the 168 without any noted trim or equipment condition, indicating a single fitment across those years regardless of headlamp type.
The rear side marker position on the Elantra GT specifies the 168 exclusively, with the condition "Without LED Tail Lights" applied to the 2014-2018 model years, indicating that vehicles equipped with LED tail lights fall outside the scope of this specification.
The 2013 model year rear side marker row carries no equipment condition qualifier, unlike the 2014-2018 entries, which each note the LED tail light exclusion.
