20" (508mm) Dual Row Viper Light Bar 32 x 3W/8 x 10W

Endurance is the name of the game. A hard-coated polycarbonate lens makes the Viper bars less prone to scratching and damage than other bars on the market — and in 508 mm this one reaches 1 lux at 734 m with 8,633 effective lumens.

Dual row is where the optics get serious. This bar carries 32 × 3 W wide LEDs plus eight 10 W long-range LEDs — twice as many of the long-range elements as any single row bar, which is why it out-throws the 40 inch single row in half the length.

1 lux at 734 m

What changed with the Viper generation

• Up to 25% more distance than the previous Lightforce bars
• Up to 25% slimmer and 25% lighter
• SMART HARNESS included — with a built-in bridge rectifier for greater compatibility with modern vehicles, and an 8-pin switch connector for factory-style switch fitment
• Bonus rear slide mounts supplied with every bar, on top of the stainless steel side brackets
• Up to 40% more affordable than the previous range

That harness matters more than it sounds. Late-model utes pulse the high-beam feed rather than running it as clean DC, which upsets a lot of aftermarket bars. The bridge rectifier in the Smart Harness is what lets this one sit behind a factory circuit without flicker.

Specifications

Where this one sits in the range

This 20 inch dual row reaches 734 m. The 30 inch single row, 284 mm longer, reaches 697 m. If bar space is your constraint, this is the better light.

Optional accessories

• LFMOUSESW — Lightforce Mouse Switch with 8-pin connector. The harness ends in an 8-pin plug, so unless you are wiring into a factory switch you will want this
• SWADP4 — harness to single switch 8-pin adaptor
• LFLBVUMKITD — universal roof mounts for dual row bars
• ATKITLBDSM / ATKITLBDEM — anti-theft kits for the dual row slide and end mounts

Frequently asked questions

Dual row or single row?
Dual row carries eight 10 W long-range LEDs against four on a single row bar, so it throws considerably further for the same length. The trade is a taller bar, more current, and a higher price.

Is the harness included?
Yes. Every Viper bar ships with the full Smart wiring harness — unlike the Lightforce driving lights, where the loom is a separate purchase.

Do I need a switch as well?
The harness terminates in an 8-pin connector. If you are not plugging into a factory-style switch, add the Mouse Switch (LFMOUSESW) or the SWADP4 adaptor, otherwise there is nothing to turn it on with.

Are the mounts included or an extra?
Included. Every bar comes with both the stainless steel side brackets and the rear slide mounts. The mount SKUs we list separately are spares and anti-theft versions.

Fitting

An LED lightbar must be wired in accordance with Warrant of Fitness rules. At 11.1 A this bar wants properly sized wiring and fusing, so if you are not sure, send us your rego and we will talk it through before you order.
