John Deere 6000, 6010 series, bulb headlight - LG8521

John Deere 6000, 6010 Series Bulb Headlight – LG8521

Keep older John Deere workhorses safe, visible and legal with this bulb-type corner bonnet headlight for 6000 and 6010 Series tractors. The LG8521 is a direct replacement for OEM reference AL78178, left-hand side, built for operators who need factory-style light output without the usual fitment headaches. Ideal for farm fleets keeping original-style halogen lighting but demanding proven reliability in daily use.

This John Deere replacement headlight exists for one simple reason: machines last longer than their lights. Lenses fade, housings crack, and suddenly night work becomes guesswork. LG8521 restores the original beam pattern and look on the left corner of the bonnet, so your tractor feels and works like it should again.

It’s engineered as a like-for-like replacement for AL78178, so mounting points, shape and connection layout are designed to match the original light unit. That matters when you’re trying to get a tractor back out in the field fast, not rewiring and redrilling. Fit it, plug it, and you’re back working.

LG8521 is suitable for a wide range of John Deere 6000 and 6010 Series models, plus selected 7000, 7010 and 6005 Series tractors, making it a solid choice for mixed fleets. Keep a pair on the shelf and you can respond quickly when a lens gets damaged or a housing fills with moisture. It’s a simple, robust solution that keeps operators visible on headlands, tracks and roads.
