40" Lethal Row Light Bar

When you're pushing deeper into the outback or tackling night runs on remote tracks, a 40" light bar gives you the kind of reach and coverage that makes all the difference. Our 40" Lethal Row light bars are built to punch serious light down the trail, whether you're running a single row for maximum throw or a dual row for broader spread.

Fitted with upgraded OSRAM P8 LED chips, these bars deliver genuine performance. The single row throws over 12,000 lumens with a 1 lux rating at 562 metres, while the dual row cranks out 21,500 lumens and reaches 758 metres. That's serious distance when you need to spot hazards, wildlife, or track conditions well ahead of where you're driving.

Installation's straightforward with sliding brackets for flexible mounting, whether you're fitting to a bull bar or roof rack. Plug-and-play wiring harnesses with Deutsch connectors mean you're not mucking around with dodgy wiring, and if you need extra length for roof-mounted setups, extension cables sort that out quickly. Interchangeable black and blue end caps let you match your rig's look, and passive heatsink cooling keeps everything running reliably in our harsh climate.

If you're after shorter options for tighter fitments, check out our 20" bars or 30" bars. And don't forget the mounting brackets and wiring accessories to complete your setup. We've also got bundles that pair light bars with driving lights and harnesses, so you can grab everything in one go.
