Hyundai Genesis front and rear side marker bulbs utilize 168 and 2357NA bulb sizes respectively. The replacement chart covers 2009 through 2014 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb follows the ANSI standard for the US and Canadian markets. It is a T10 miniature wedge type rated at 12V and 4.9W, placing it in the low-wattage category typical of parking and marker lamp applications.
The Hyundai Genesis uses the 168 bulb for the front side marker position across all six model years covered, spanning 2009-2014, with no variation in bulb size across that range.
The 2357NA bulb also conforms to the ANSI standard for the US and Canadian markets. It uses a BAY15d bayonet base and features a dual-filament design rated at 12V with a high-intensity filament drawing 26.9W and a low-intensity filament drawing 8W. The natural amber glass produces the amber color required for side marker use without relying on a colored lens.
The dual-filament construction of the 2357NA means the two filaments serve distinct brightness levels, a configuration that differs fundamentally from the single-filament 168 used at the front. These two bulb types are not interchangeable with each other due to differences in base type, wattage, and filament count.
The rear side marker position on the Hyundai Genesis uses the 2357NA, but fitment is subject to production date restrictions on certain model years. The 2014 model year applies only to vehicles produced up to January 17, 2014, and the 2011 model year applies only to vehicles produced from February 21, 2011 onward.
The BAY15d bayonet base of the 2357NA has two offset pins that prevent incorrect single-filament bulbs from being seated in the socket, as the pin positions are keyed to the dual-filament configuration.
