John Deere Gator XUV 625i 4x4 Turn Signal Bulb Size
John Deere Gator XUV 625i 4x4 front and rear turn signal bulbs utilize a 3157NA bulb size. The replacement chart covers 2011 through 2016 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 John Deere Gator XUV 625i 4x4 uses the 3157NA bulb type for both its front and rear turn signals across the 2011-2016 model years.
The 3157NA is a dual-filament bulb, meaning it contains two separate filaments within a single housing. The higher-wattage filament operates at 27W and the lower at 7W, allowing one bulb to serve both a steady and a flashing or reduced-intensity function.
The 3157NA follows the ANSI standardization system, which governs bulb base dimensions, voltage, and wattage ratings for the United States and Canada.
The bulb carries a T25 designation, which refers to its wedge-style base form factor. This base type is pressed directly into a socket rather than twisted, which is a common trait in automotive turn signal applications.
The "NA" suffix in the 3157NA designation indicates natural amber glass. The amber coloring is built into the glass envelope itself rather than applied as a coating, which produces the amber light output required for turn signal use.
The bulb operates on a 12V electrical system, consistent with standard automotive and utility vehicle electrical architecture.
The 3157NA shares its physical base with the broader 3157 bulb family. However, substituting a clear-glass 3157 for the 3157NA would change the light output color, which may affect compliance with turn signal visibility standards.
