Matching an electrical part to the tractor

Check three things before ordering: system voltage, connector type and, for John Deere parts, the part number on the old unit. Every product page states the voltage in its specification, names the connector where the manufacturer gives it, and lists equivalent and superseded part numbers. John Deere parts carry a fitment list by tractor model, and the filters on each page narrow the range by make and model. Hella electrical parts are E-marked where the part is on the road-legal circuit, and the part number on the product page matches the Hella catalogue number. The lamps these parts serve are under tractor lighting, and the consumables for the same job, cable ties, heatshrink and insulating tape, are under workshop and consumables.
