The first thing to do is figure out the functions of the wires on your Kubota. Using a circuit tester such as # PTW2993 or a meter if you have one you can test each wire while someone operates the various light functions.

On light # STL72RB you would use pigtail # A45PB. On it the white wire is ground, the black wire is for tail/running lights, and the red wire is for combined turn signal and brake lights. Once you know the functions of the wires on your lights you can match them up to the wires described above.

If your existing lights have another function (reverse lights) or has separate turn signals from the brake lights then these lights will not work. We do have a similar light with reverse # STL211RB and you would need to use 2 of the pigtails for every 1 of these lights.
