Tractor lighting guides
Tractor lighting guides are plain-English answers to the questions farmers, contractors and dealers ask us about beacons, work lights, headlights, rear lights and bulbs. Each guide covers what the law requires on UK roads, how to choose between LED, halogen and xenon, how to wire and fit the lamp, and which parts fit which tractor. The guides are written by the Agri Lighting team in Lincolnshire, whose parts business has supplied farms since 1996.
