ARB Intensity V2 Driving Lights: 4Runner Winter Review

ARB Intensity V2 driving lights are premium LED auxiliary lights built for trucks and SUVs that need to see far beyond their factory headlights — exactly the reach you want on a dark, snow-covered winter road. When the sun sets at 5 p.m., the plow trucks are down and black ice is hiding in the shadows, a set of ARB Intensity lights on your Toyota 4Runner turns a nervous crawl into a confident drive. We run these lights on shop trucks here in the winter test loops, and in this review we break down the full ARB Intensity V2 and SOLIS lineup, the spot-versus-flood decision that actually matters in snow, and how to wire and aim them for cold-weather driving.

What Are ARB Intensity Driving Lights?

ARB Intensity driving lights are round LED auxiliary lights designed to extend a 4x4's usable sight distance far past the reach of stock headlights. ARB — the Australian off-road brand behind bull bars, air lockers and rooftop tents — builds the Intensity line around OSRAM GIANTS high-output LEDs, high-pressure cast-aluminum housings and a virtually indestructible polycarbonate lens. The current generation splits into two families: the Intensity V2 (available in 32-LED and 21-LED sizes) and the newer Intensity SOLIS 36. Every model is rated IP68 for full submersion, runs a 5700K daylight-white color temperature, and accepts 10–36 volts — so the same light works on a 12V 4Runner or a 24V rig.

For winter driving specifically, that engineering matters. An IP68 seal shrugs off salt spray, slush and repeated trips through the car wash. The cast-aluminum body and active thermal management keep the LEDs from cooking themselves, and the SOLIS is validated to operate from -40°C to +65°C — it fires up the same in a Minnesota cold snap as it does in the Outback.

Why Do You Need Auxiliary Driving Lights in Winter?

Auxiliary driving lights matter most in winter because winter is when you drive the most miles in the dark, on the worst surfaces, with the least warning. In December, many parts of the country lose daylight before the evening commute even ends. Factory high beams on a 4Runner, Tacoma or F-150 typically light the road to roughly 100–150 meters — fine at 35 mph, not enough to spot a deer, a snowdrift or a stalled car at highway speed on an unlit county road. A pair of ARB Intensity V2 32 Spots pushes usable light out to nearly 800 meters, giving you the seconds you need to react before you are on top of a hazard.

There is also a color-temperature advantage. The Intensity's 5700K daylight-white output renders contrast far better than the yellow-tinged halogens in older trucks, so black ice sheen and packed-snow ruts show up sooner and your eyes fatigue less on a long, dark drive home. And because these are sealed, cast-metal lights — not cheap plastic pods — they survive the salt, slush and freeze-thaw cycles that destroy bargain lighting by February.

ARB Intensity V2 32 Spot Review: The Winter Distance King

The ARB Intensity V2 32 Spot is the light we reach for first on a winter build. Its Hyperspot optics concentrate 20,000 raw lumens (7,452 effective) into a tight, pencil-thin beam that reaches 795 meters at 1 lux — the kind of throw that turns an unlit rural highway into a lit runway. It draws 165 watts across a 10–36V range, seals to IP68 (submersible to 3 meters), and wraps its OSRAM GIANTS LEDs in a high-pressure cast-aluminum body. At around $844 it is not cheap, but it is a buy-once light.

Spot vs Flood vs Combo: Which Beam Is Best for Snow?

For falling snow and fog, a flood (wide) beam is safer than a pure spot, but the ideal winter setup is a spot-and-flood combo. Here is why: a tight spot beam throws a narrow column of light straight down the road, which is perfect on a clear, cold night but works against you in active snowfall. All those bright snowflakes reflect the concentrated beam straight back at you — the "snow-globe" glare-back effect — and you end up seeing the storm instead of the road. A flood beam spreads the light wide and low, lighting the surface and shoulders without blasting a wall of reflection back into your eyes.

That is exactly why ARB sells the Intensity in matched spot and flood versions. Run one V2 32 Spot and one V2 32 Flood side by side and you get long-range reach for open highway plus the shoulder-to-shoulder wash you want in a squall — the combo ARB itself recommends. If you can only mount one light on a compact bumper, choose the flood for winter; it is the more forgiving beam when the weather turns.

The Full ARB Intensity Lineup for Winter Builds

Beyond the flagship V2 32, ARB offers two more Intensity options that fit different budgets and bumpers. The Intensity SOLIS 36 is the newest platform and the distance champion; the Intensity V2 21 Flood is the compact value pick for tighter mounting spots. Both share the same IP68 sealing and 5700K daylight color as the 32.

ARB Intensity SOLIS 36 Spot Kit (with Loom)

The SOLIS 36 Spot Kit is the longest-throwing light in the family, punching a 6-degree beam out to 1,032 meters at 1 lux from 18,178 raw lumens (9,546 effective). It runs 36 OSRAM LEDs (six 10W plus thirty 4W), draws 165 watts (12.4 amps at 13.2V), and is rated from -40°C to +65°C with IP68 submersion to nine feet. Because this is a two-light kit that ships with the wiring loom, it is the easiest way to add a matched pair to a winter rig in one box — around $723 for the set.

ARB Intensity V2 21 LED Flood (Compact Value Pick)

The Intensity V2 21 Flood is the budget-friendly, space-saving option at around $565. It still delivers 13,170 raw lumens (9,100 effective) from a smaller 7.25 x 8.2 x 4.6-inch body, draws just 105 watts, and pushes a wide fill beam to roughly 555 meters (1,821 feet) at 1 lux. Its compact footprint makes it the easy choice when a full-size 32 will not clear your grille, license plate or a stubby winter bumper — and the wide flood pattern is exactly what you want for close-in snow and slush.

ARB Intensity Comparison: Which One for Your Winter Rig?

Here is how the four ARB Intensity models compare on the specs that matter for a snow-season build. Beam pattern drives the winter decision more than raw output: spots for open-highway distance, floods for falling snow and close-in coverage.

How to Mount and Aim ARB Intensity Lights for Winter

Auxiliary driving lights must be wired to a relay and switch and can only legally be used with your high beams, off public roads or where local law allows. On a Toyota 4Runner, Tacoma, Wrangler or F-150, the cleanest mounting points are an ARB bull bar with integrated light tabs, a bumper hoop, or a roof rack; ARB offers vehicle-specific brackets for many platforms so you are not drilling your bumper. Plan your mount before you buy so the light clears the grille and does not block airflow to the radiator.

For wiring, run the included or an ARB-spec harness with an inline fuse, a relay triggered off the high-beam circuit, and a dash switch. In winter, route and secure the loom away from areas that pack with ice, and use dielectric grease on the connectors to keep road salt from corroding the terminals. Aim the lights on a flat surface at night: point spots slightly above the road's vanishing point for maximum distance, and set floods lower and wider to light the shoulders and immediate surface. If you run a spot-flood combo, aim the flood a touch lower so it fills the foreground the spot leaves dark.
