Hyundai Santa Fe Brake Bulb Size

Additional Notes

• The 1157 is the most frequently specified brake bulb across the Hyundai Santa Fe lineup, appearing across the widest range of model years. It is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and 5W low filament, and it conforms to ANSI standards used in the United States and Canada.
• The 2357 and 2057 share the same BAY15d bayonet base as the 1157 and operate at 12V, but both draw more power at 26.9W on the high filament and 8W on the low filament, making them higher-output alternatives within the same base family. Despite this physical compatibility, substituting one for another without confirming the vehicle's specific requirement is not advised, as each is listed as a distinct fitment.
• The 2019-2020 model years carry a conditional fitment note, specifying the 1157 only for vehicles equipped with halogen capsule headlamps. The 2013-2016 model years carry the same conditional note but specify the 2057 instead.
• The center high mount stop light on the Hyundai Santa Fe (2007-2012) uses the 168, a miniature T10 wedge bulb rated at 12V and 4.9W. Earlier model years from 2001-2006 use the 921, a T15 wedge bulb rated at 12V and 16W, representing a notably higher wattage for the same lamp position.
• The 12961 is listed for the inner brake position on the 2021 and 2023 Santa Fe. It is a Philips part number rather than an ANSI designation, specifying a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
• The 168 and 12961 share the same T10 form factor but carry different base designations. The 168 uses a standard wedge base, while the 12961 specifies a W2.1x9.5d base. These two bulbs serve different lamp positions and are not listed as interchangeable within these specifications.
