40 Watt LED Cab Insert Light - LG841

40 Watt LED Cab Insert Light – LG841

Tired of dim, fragile cab lights holding you back during long nights in the field? This is your solution. The LG841 is a direct-fit 40W LED insert, engineered to drop straight into the original housing on a wide range of Massey Ferguson tractors for a fast, no-fuss upgrade. It is fully approved to ECE R10 and EMC CISPR 25 Class 4 standards, guaranteeing zero interference with your GPS, telematics, or radio.

We designed this light for one reason: to eliminate downtime. When you’re up against the clock, the last thing you need is a failed lamp or a complicated rewiring job. The LG841 is a true plug-and-play replacement. It uses the supplied DT connector to plug directly into your tractor’s existing harness, turning a workshop task into a simple, minutes-long swap. The powerful 3,200 lumen output delivers a clean flood beam, bathing your work area in crisp, 6,000 K cold white light for exceptional clarity and reduced operator fatigue.

A hard-working machine needs a hard-working light. That’s why the LG841 is built to withstand the toughest agricultural environments. The housing is machined from rugged die-cast aluminium, paired with a shatterproof polycarbonate lens. It's rated to IP68, meaning it is completely sealed against dust and can handle sustained water immersion and high-pressure washing. We’ve also tested it to withstand 15G of vibration, so it won't fail you on rough terrain.

Here's the thing about modern tractors: their electronics are sensitive. That’s why we take electromagnetic compatibility so seriously. This light isn't just ECE R10 approved; it meets the stringent CISPR 25 Class 4 standard. Put simply, it means you can run your lights, your radio, and your GPS without a single crackle of static. It's engineered to be electrically silent, protecting your investment in precision farming technology. With a 50,000-hour service life and a wide 9–32 V DC operating range, it’s a fit-and-forget solution you can depend on.
