20" Lethal Row Light Bar

A 20" light bar is one of the most versatile lighting upgrades you can bolt to your 4WD. Compact enough to fit almost anywhere but powerful enough to punch serious light down the track, it's the sweet spot for drivers who want better visibility without the bulk of a larger bar.

Our 20" Lethal Row range delivers serious output thanks to upgraded OSRAM P8 LED chips. Single row bars pump out over 6,500 lumens with a throw distance beyond 400 metres, while dual row versions crank things up past 11,000 lumens with even greater reach. That's real-world visibility when you're threading through bush tracks at dusk or navigating sandy tracks after dark.

Every bar comes with sliding brackets for flexible mounting, interchangeable black and blue end caps, and water resistant Deutsch-style connectors. The included hardware means you're not chasing extra bits, and the passive cooling heatsink keeps everything running smooth even when you're hard on the throttle for hours.

Whether you're mounting it on a bull bar, roof rack, or canopy, a 20" bar slots in neatly without dominating your setup. And if you're building out a full lighting system, pair it with mounting brackets and wiring accessories to get everything dialled in. Looking for more coverage?
