Would you have a link to the instructions please.
The Kubota LED work lights from my dealer are wired to the light feed wires that are hidden at the rear tail lights on our BX tractors. The install instructions from Kubota had me to wire them into the spare bullet connector that is located in the tail light area. This power is switched with the rest of the headlights, but they also had on/off switches in the mount brackets so that you can cut them off if you do not wish for them to be on with the headlights.
