John Deere Gator TS 4x2 Vehicle-Mounted Spotlight Bulb Bulb Size
The John Deere Gator TS 4x2 vehicle-mounted spotlight bulb requires an H1 size for proper installation and operation within the specified lighting assembly. Data for the lighting components covers the range from 2010 through 2017 for the specified utility vehicle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The John Deere Gator TS 4x2 uses the H3 bulb size for both the front and rear vehicle-mounted spotlight positions across the 2010-2017 model years.
The H3 is a single-filament halogen bulb operating at 12V and 55W, built to the ECE standard with approval in the US and Japan, and it uses a PK22s base.
The PK22s base on the H3 is a pinch-base connector, meaning the bulb is held in place by a metal cap rather than a screw or bayonet fitting, which affects how it seats in the housing.
The beacon revolving light kit bulb position on the Gator TS 4x2 calls for the H1 size across the 2010-2017 model years.
The H1 shares the same 12V, 55W rating and single-filament halogen construction as the H3, and it also meets ECE standards with US and Japan approval, but it uses a P14.5s base rather than the PK22s found on the H3.
The P14.5s base on the H1 is a single-pin base, which is physically incompatible with the PK22s socket used by the H3, making the two bulb types non-interchangeable despite their identical wattage and voltage ratings.
Because the H1 and H3 share the same power draw, the electrical load on the Gator TS 4x2 circuit is consistent across the spotlight and beacon positions, though the differing base types prevent cross-position substitution.
The consistent use of H3 across both the front and rear spotlight positions for the full 2010-2017 range indicates a single bulb specification covers both locations on this vehicle.
