40 Watt LED Standard Mount Oval Work Light – LG839
A direct, OEM-quality upgrade for your tractor's weak halogen work lights. The LG839 is engineered to fit a huge range of Massey Ferguson, Deutz-Fahr, and Same models, delivering a powerful 3,200-lumen flood beam with a simple plug-and-play connection. It’s built to work hard and, crucially, to work quietly—fully approved to ECE R10 and CISPR 25 Class 4 for guaranteed zero radio or GPS interference.
Don't let failing lights stop your work. We designed the LG839 to solve a common, costly problem: the premature failure of original-equipment work lights on high-value agricultural machinery. It’s engineered as a direct drop-in replacement, matching the oval form factor and standard mount of hundreds of tractor models. Installation is simple. It uses an integrated DT 2-pin plug, so there’s no cutting or splicing. Just unplug the old unit, bolt in the new one, and get back to work.
This is more than a replacement; it’s a serious upgrade in performance and durability. The 40-watt LED chipset produces a crisp, clear 3,200 lumens in a wide flood beam, turning night into day and illuminating the entire work area in front of you. The housing is built from tough, powder-coated die-cast aluminium, sealed to an IP68 rating. That means it’s completely dust-tight and can handle prolonged submersion and high-pressure jet washing without issue. And it’s built to handle the roughest field conditions, having been tested to a punishing 15 G for vibration resistance.
Here’s the thing about modern tractors: they’re packed with sensitive electronics. That’s why we engineered the LG839 for complete electrical silence. It’s not just approved to the ECE R10 standard; it meets the exceptionally strict EMC CISPR 25 Class 4 rating. This is your guarantee of zero interference with GPS, telematics, or radio communications. With a wide 9–32 V DC operating range, it delivers stable, flicker-free performance on any 12 V or 24 V system.
