Unit price per
Punch through nature's cloak. Lightforce's own line for the 10 inch single row, and it fits: bulk out your reversing lights, or add some wattage to the bull bar. 254 mm, 798 g, and 1 lux at 372 m from ten 5 W Osram Oslon LEDs.

1 lux at 372 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.

Key features
- SMART HARNESS with 8-pin switch connector for easy factory switch fitment
- Osram Oslon LEDs for greater performance, contrast, and less driver fatigue
- Durable AkzoNobel powder coat finish, tested to Australian Standard AS1580, for protection against UV and salt water
- RF shielding technology reduces radio interference
- Waterproof to 1 metre with a genuine Gore breather
- Screwless front bezel, so the face stays clean and there is nothing to corrode
- Lightweight slimline housing with stainless steel side brackets
- Polycarbonate lens

In the box
- 1 × Viper 10 inch single row LED light bar
- Stainless steel side brackets and fixings
- Rear slide mount brackets and fixings
- 1 × full Smart wiring harness
- 1 × Torx key
- User instructions
Both bracket types are in the box, so you can decide on the vehicle whether to side mount or slide mount.

Where this one sits in the range
| Single row | 6″ 256 m · 10″ 372 m · 20″ 562 m · 30″ 697 m · 40″ 793 m · 50″ 878 m |
|---|---|
| Dual row | 10″ 454 m · 20″ 734 m · 30″ 896 m · 40″ 984 m · 50″ 1,065 m |
The 10 inch dual row is the same length but reaches 454 m instead of 372 m, for about $50 more. If the mounting space is fixed and you want the output, that is the better buy.
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
- ATKITLBSSM / ATKITLBSEM — anti-theft kits for the single row slide and end mounts
- LFVEMS — spare single row end mounts
Frequently asked questions
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 slide 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.
Single row or dual row?
Dual row puts two rows of LEDs behind the same length of lens, so you get more output and more reach from the same mounting space, at a higher price and a taller bar. Single row is slimmer and tucks away better.
Will it work on a late-model ute?
That is what the Smart Harness is for. Its built-in bridge rectifier handles the pulsed high-beam feeds used on many modern vehicles.
Fitting
An LED lightbar must be wired in accordance with Warrant of Fitness rules. If you are not sure how it should be switched on your vehicle, send us your rego and we will talk it through before you order.
