To avoid the high summer temperatures, I often start my tractor work before the sun rises. Therefore I need lights forward and aft. I found that the OEM Kubota work lights were useless for my use. I ordered two 75 watt LED light bars from Amazon, $50.
Rather than deal with the installed, light guage wiring, I ended up routing power myself. Mounted two switched on dash, then 14 ga power fore and aft to the new lamps. I used the supplied ground in the OEM harness, a white/black wire of 14 ga. On the exterior, the only visible change are the two cables carrying power are within a 1/4” plastic conduit on the right ROPS riser.
Those LED light bars really do the trick, and are way less expensive.
