John Deere Gator TH 6x4 Vehicle-Mounted Spotlight Bulb Bulb Size
The John Deere Gator TH 6x4 vehicle-mounted spotlight bulb utilizes H1 as the specific bulb size for the lighting component. Data for the lighting specifications covers the range from 2010 through 2016.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The John Deere Gator TH 6x4 uses the H3 bulb size for both the front and rear vehicle-mounted spotlight positions across the 2010-2016 model years.
The H3 is an ECE-standard single-filament halogen bulb rated at 12V and 55W, fitted with a PK22s base. The ECE standard indicates approval for use in Europe, the US, Japan, and worldwide markets.
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. This base type is specific to the H3 and is not interchangeable with other halogen base types.
The beacon revolving light kit bulb position on the Gator TH 6x4 uses the H1 size across the 2010-2016 model years.
The H1 is also an ECE-standard single-filament halogen bulb rated at 12V and 55W, but it uses a P14.5s base rather than the PK22s base found on the H3.
Although the H1 and H3 share the same voltage and wattage ratings, their bases are physically different and the two types are not interchangeable with each other.
The P14.5s base on the H1 is a single-pin base, distinguishing it from the pinch-style PK22s base of the H3. Substituting one for the other is not possible without a physical mismatch at the socket.
All three bulb positions on the Gator TH 6x4, front spotlight, rear spotlight, and beacon revolving light kit, operate on a 12V electrical system, consistent across the full 2010-2016 span covered in the specifications.
