The NACHO Quatro packs an unusual amount of technology into a 4" pod. This is the combo set, supplied as a pair, producing 14,400 raw lumens and 10,486 effective lumens across the pair and reaching 352 m (1,155 ft) at 1 lux.
What sets the Quatro apart from a generic pod is the Trail Running Light, a white back-lit element designed to make you visible in daylight, and the swappable covers that come in the box. The body is powder-coated aluminum with a pressure equalizing vent, the lens is polycarbonate, and NACHO rates the light to IP68 and to SAE J575 for vibration.
Each light weighs 1.2 lb and draws up to 60 W at maximum in any mode.
What's Included:
Two NACHO Quatro LED lights
Stainless steel universal mount brackets with chrome plated hardware
Two amber covers
Two smoke covers
Features
Trail Running Light A white back-lit element designed as a Trail Running Light, adding daytime visibility and a distinctive signature without running the main beams.
Combined spot and flood Optics A precision combo beam pairing TIR spot optics with lenticular flood technology, giving wide coverage and a focused down-range spot from a single light.
Pressure Equalizing Vent The vent lets the light breathe as it heats and cools, which stops the internal vacuum that pulls moisture past seals. It is the detail that separates a light that stays clear from one that fogs internally after a season.
IP68 And J575 Vibration Rated IP68 for dust and water ingress, and SAE J575 for vibration. The second one is what matters when a light is bolted to a bumper over corrugations at speed.
Powder Coated Aluminum Heat Sink An aluminum heat sink with a polycarbonate lens for impact protection, which is the right combination: metal where you need thermal conductivity and polycarbonate where you need something that takes a stone.
Four Covers In The Box Two amber and two smoke covers are supplied, so you can change the look and the beam color without buying anything extra. Amber is the practical choice for dust and fog.

Installation
Type: Bolt-on pair with universal stainless brackets, wired to a switched circuit · Time: 1-2 hours per pair including wiring · Tools: Socket set, crimper, cable ties, drill if the mounting point needs one · Difficulty: Moderate
The lights themselves are a bolt each through a stainless bracket. The wiring is the work: these are high-output lights and need a properly fused, relayed circuit. The NAC11N 40 amp harness is built for exactly this job and includes the switches. Aim the beam on a dark road once everything is torqued down.
Warranty, Shipping & Returns
Warranty. NACHO states a lifetime warranty against manufacturing defects on this product, and the distributor record independently lists the warranty term as Lifetime. Those are the two sources available and they agree. In North America it is supported through ARB (Air Locker Inc., Auburn, WA) and honored through authorized dealers like us. We describe the warranty exactly as the manufacturer publishes it and do not extend or restate its terms.
Free shipping. This item ships free to the lower 48 states and typically arrives in 3 to 7 business days.
Inspect on delivery. Please inspect your order on arrival. If anything is damaged or missing, contact us right away and we will make it right.
Compliance. NACHO publishes ECE R10 electromagnetic compliance, IP68 ingress protection and SAE J575 vibration rating for this light. No SAE beam certification is published for this variant, so it is sold as an off-road auxiliary light.
About ARB
NACHO Offroad Lighting is ARB's American lighting brand, engineered, tested and built in the USA and proven at events like King of the Hammers and the Baja 1000. NACHO products are designed around user control: programmable output modules, replaceable housings and swappable covers, so one light can serve as a driving light, a work light or a street legal fog lamp depending on how you set it up.
NACHO sits inside the wider ARB group, which began in a Melbourne driveway in 1975 and is now the largest 4x4 accessories manufacturer in the southern hemisphere, with offices in the USA, Europe and the Middle East. Prestige Truck is an authorized ARB and NACHO dealer. Every light we ship is genuine US market stock with full manufacturer warranty support behind it.

Frequently Asked Questions
Straight answers on specs, fit and support
Is this one light or a pair?
A pair. That matters when you compare the price against a single-light listing elsewhere. It also matters when you read the specification: the lumen and beam distance figures NACHO publishes for this part number are measured for the pair at maximum output, while the 1.2 lb weight is for a single light.
What is the Trail Running Light for?
It is a white back-lit element that runs as a daytime running light, making the vehicle more visible in daylight without switching on the main beams. It runs off its own circuit, which is why the NACHO NAC11N harness includes a dedicated green wire for it.
Which Quatro should I buy?
NACHO makes four in this range and they differ by optics: the combo (PM411) mixes spot and flood, the spot (PM431) concentrates into roughly 10 degrees for distance, the flood (PM451) spreads wide and close, and the SAE combo (PM461) trades some raw output for a road-legal fog pattern. This is the combo. All four are the same physical light with different optics behind the lens.
Do I need a special harness?
You need a properly fused and relayed circuit, and NACHO makes one for the job: the NAC11N is a dual 40 amp harness with two Carling switches and a dedicated green wire for the Quatro Trail Running Light. A generic harness will run the main beams but will not have the extra circuit for the running light.
What covers come with it?
Two amber and two smoke covers are in the box, so a pair of lights can be run in either finish without buying anything. Amber is the useful one in dust and fog; smoke is cosmetic and reduces output.
What is the warranty?
NACHO publishes a lifetime warranty against manufacturing defects on this product, and the distributor record independently records the term as Lifetime. Two sources, in agreement. If something is wrong with how it was made, contact us and we will take it up with the manufacturer. Keep your invoice.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
