A lot of folks here add or upgrade their tractor lights to led, myself included. I used 55w, 9", spot / flood combo LEDs on my tractor cab x4. They are game changers when working at night, and practically turn night into day out to maybe 30' or so.
I ordered my *Kubota with OEM cab lights for the switches and brackets. It was an easy upgrade. I also swapped all other bulbs to LEDs (except the corner lights that are useless with a loader) and the reduced amp load is significant.
