John Deere Gator XUV 825i 4x4 Turn Signal Bulb Size
John Deere Gator XUV 825i 4x4 front turn signal bulbs use 3157NA size, while rear turn signal bulbs use 1157 or 3157NA size. The replacement chart covers 2011 through 2017 production 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 John Deere Gator XUV 825i 4x4 front turn signal position uses the 3157NA bulb across all model years from 2011-2017.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and 7W low filament, constructed with natural amber glass that produces a yellow-orange output without the need for an amber-tinted lens.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and 5W low filament, and it relies on a clear or colored lens to produce the appropriate signal color rather than tinted glass.
Both the 3157NA and 1157 conform to ANSI standards applicable in the United States and Canada.
The rear turn signal position on the Gator XUV 825i 4x4 does not use a single bulb type across all years, with the 3157NA fitted in 2012 and 2016, and the 1157 fitted in 2011, 2013-2015, and 2017.
The 3157NA and 1157 are not interchangeable, as the 3157NA uses a wedge-style base while the 1157 uses a BAY15d bayonet base, meaning the socket type in the housing determines which bulb is compatible for a given model year.
The wattage ratings differ between the two bulb types, with the 3157NA drawing more power on its high filament (27W) compared to the 1157 (21W), which reflects a difference in light output between the two.
