The Hyundai Elantra GT tail light requires a 2357 bulb size for proper installation and function within the rear lighting assembly. Data for the specified component covers the period from 2013 through 2020.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Elantra GT inner tail light position uses two distinct bulb types across its model years: the 12961 and the 168, with fitment determined by the vehicle's lighting configuration rather than the model year alone.
The 168 is an ANSI-standard miniature wedge bulb rated at 12V and 4.9W, while the 12961 is a Philips-designated T10 wedge bulb sharing the W2.1x9.5d base and rated at 12V and 5W. Both occupy the same T10 form factor, though they carry different part designations and wattage ratings.
The inner tail light on the 2018-2019 Elantra GT with halogen capsule headlamps takes the 12961, whereas the same position on vehicles without LED tail lights from 2014-2018 takes the 168. The 2013 model year uses the 168 without a stated trim condition.
The 2357 is the sole bulb type specified for the outer tail light position across all listed model years of the Elantra GT, from 2013 through 2020.
The 2357 is a dual-filament bulb using a BAY15d bayonet base, rated at 12V with a high filament draw of 26.9W and a low filament draw of 8W. This dual-filament design allows a single bulb to serve both steady and flashing or braking functions within one housing.
The 2357 is described as a brighter variant of the 1157, which shares the same BAY15d base. The two types are physically interchangeable in many applications, but the 2357 draws more current on its high filament, which can affect compatibility with certain vehicle circuits.
The 2014 outer tail light entry carries a production date qualifier of "From 4/30/2012," indicating that the 2357 fitment applies only to vehicles built on or after that date within the 2014 model year production run.
Vehicles equipped with LED tail lights are excluded from the halogen bulb fitment data for the inner tail light position in the 2014-2018 model years, as those configurations do not use a replaceable halogen bulb in that location.
