Hyundai Veloster N front turn signal uses 2357NA bulb size while rear turn signal uses 1156NA bulb size. The replacement bulb chart covers 2019 to 2022 production years with corresponding specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 2357NA is a dual-filament bulb operating at 12V with a high/low wattage rating of 26.9W and 8W respectively, housed in a BAY15d bayonet base with natural amber glass. It conforms to ANSI standards used in the United States and Canada.
The 1156NA shares the same ANSI standard classification and natural amber glass construction as the 2357NA but differs in that it is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The PY21W follows ECE standards applicable to European and international markets. It is a single-filament amber bulb rated at 12V and 21W, using a BAU15s bayonet base.
The BAY15d base of the 2357NA, the BA15s base of the 1156NA, and the BAU15s base of the PY21W are physically distinct from one another. These differences in base type make the three bulbs non-interchangeable despite some sharing the same voltage and wattage ratings.
The Hyundai Veloster N uses the 2357NA for the front turn signal and the 1156NA for the rear turn signal across the 2019-2020 and 2022 model years.
The 2021 model year specifies the PY21W for both the front and rear turn signal positions, representing a departure from the ANSI-standard bulbs used in surrounding model years.
The front turn signal position requires a dual-filament bulb (2357NA) in three of the four model years listed, while the rear turn signal position uses only single-filament bulbs across all listed model years.
The amber coloring in the 2357NA and 1156NA is achieved through natural amber glass rather than a coating or tinted lens, which is the standard method for ANSI-designated "NA" bulbs.
