Complement your spotlights and get more width of beam on the track — while still using the AM or UHF radio without the ear-splitting interference. 1,046 mm, 1 lux at 984 m, and 15,572 effective lumens.
72 × 3 W wide LEDs plus eight 10 W long-range LEDs. That RF shielding claim is not filler on a bar this size — 42,456 raw lumens of switching current sitting on your roof is exactly the thing that wipes out a UHF, and Lightforce have engineered around it.
1 lux at 984 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 308 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.

- SMART HARNESS with 8-pin switch connector for easy factory switch fitment
- Osram Oslon LEDs for greater performance, contrast, and less driver fatigue

Frequently asked questions
Will it interfere with my UHF?
That is what the RF shielding is for. Cheap bars are notorious for it; Lightforce build the shielding in and quote reduced radio interference as a feature of the range.
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 308 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 20.1 A this bar draws serious current — it needs properly sized cable, a relay and correct fusing. Send us your rego and we will talk it through before you order.
