The Hyundai Entourage front turn signal requires a 2357NA bulb size while the rear turn signal uses a 1156NA bulb size. The replacement chart covers 2007 to 2008 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Entourage uses the 2357NA bulb for the front turn signal across the 2007-2008 model years. This is a dual-filament bulb rated at 12V with a high filament draw of 26.9W and a low filament draw of 8W, housed in a BAY15d bayonet base.
The rear turn signal on the 2007-2008 Entourage takes the 1156NA bulb, a single-filament type rated at 12V and 21W with a BA15s bayonet base.
Both the 2357NA and 1156NA carry the NA suffix, which denotes natural amber glass. This coloring produces the amber signal output directly from the bulb rather than relying on a colored lens.
The BAY15d base of the 2357NA and the BA15s base of the 1156NA are physically incompatible with each other. The BAY15d features offset locating pins to accommodate its dual-filament design, while the BA15s uses a single-pin configuration suited to a single filament.
Both bulbs conform to ANSI standards recognized in the United States and Canada, indicating they meet regulated performance and dimensional criteria for those markets.
The 2357NA shares its BAY15d base with the widely used 1157 bulb family, but the two are not interchangeable without confirming wattage compatibility, as filament ratings differ between variants in that family.
The single-filament 1156NA at the rear serves only the turn signal function, whereas the dual-filament 2357NA at the front is capable of supporting two separate lighting functions through its high and low filament circuits.
