Everything You Need to Know About IP67 Forklift Lights

Forklift lights are used in order to help drivers and operators see what is in front of them, but you can also buy additional lights to help other workers steer clear of the forklift when it is cruising on through a narrow aisle way or space. All businesses with forklifts are required to own a set of light for each vehicle they use.

If you are in need of a new set of forklift warning lights, you'll see that some of them come with additional benefits or features. One of these features is that they are IP67 waterproof. If you are curious about waterproof lights, what IP67 means, and want to know some instances where it would be great to have waterproof lights, we can explain all of this to you here.

What Is an IP67 Forklift Light?

An IP67 forklift light is a warning or work light that is fully dust-tight (the "6") and can survive submersion in up to 1 metre of water for 30 minutes (the "7") without water reaching the electronics. In a warehouse, that translates to a light that shrugs off dust, condensation, rain, wash-down spray and the occasional dunk in a drain or tank - instead of fogging over, corroding and dying six months after installation.

If you only take one thing from this article: IP67 is a laboratory result, not a marketing word. Ask the supplier which standard it was tested to (IEC 60529) and whether the housing, lens, gasket and cable entry were all tested as one assembly.

Why Are Some Forklift Lights Waterproof?

It might sound random to think that forklift lights of all things are waterproof, but as with other electronics and devices, more and more products are becoming waterproof and can be submerged in water for a period of time before the product fails. Today's forklift lights have reinforced housing so that it takes longer for less water to get inside. Even if the forklift light remains on when submerged underwater, the light will continue to shine for a while before enough water gets inside the housing.

It's important to know that waterproof doesn't exactly mean free of water. Some products marked waterproof will be less tolerable to water than others. Professional products will tend to have a "grade" of waterproofing where you can easily find out what water pressure can a product tolerate and for how long.

What Actually Destroys a Forklift Light (It's Usually Not a Flood)

In real North American facilities, sealed lights rarely fail from one dramatic soaking. They fail from a slow accumulation of small exposures:

• Condensation cycling

A forklift runs from a −20 °F freezer into a 75 °F dock ten times a shift. Warm, humid air gets pulled into any light with an imperfect seal, then condenses on the cold lens. Over weeks, that moisture pools inside and corrodes the driver board.

• Pressure washing

Sanitation crews hit machines with hot, high-pressure water. This is a jet problem, not an immersion problem - and as we explain below, IP67 alone does not promise jet resistance.

• Vibration loosening the seal

A forklift mast is a punishing place to live. Vibration slowly relaxes gaskets and backs out fasteners, opening a path for water that wasn't there on day one.

• Chemical attack

Sanitizers, brine, fertilizer dust and battery acid degrade cheap silicone gaskets and polycarbonate lenses far faster than plain water does.

• The cable entry 

The most common leak point on any light isn't the lens - it's where the wire enters the housing. Potted, strain-relieved cable entries are the difference between a three-year light and a three-month light.

This is exactly why the entire BEAST forklift lighting range is built around sealed, potted housings rather than snap-together plastic shells.

What Does IP67 Mean?

IP67 is a code that is issued by the International Electrotechnical Commission (IEC). This code and others are given to products that undergo dust and waterproof testing.

"IP" stands for Ingress Protection (or International Protection) and doesn't have any other variables.

The first digit, that being 6, refers to the protection of dust and other solid particles. That means the forklift lights can manage to keep dust out of its housing. 6 is the highest grade.

The second digit refers to protection against water and other liquids, in which case many forklift lights will tend to score a 7. Products that score a 7 can be submerged into a body of water up to one yard deep, and can stay operational for half an hour. They can also endure forceful water jets.

A forklift warning light rated IP67 can tolerate a lot of water before failing due to the effects of submersion, meaning it will hold up pretty well in light of most water-related incidents.

IP67 vs IP65 vs IP68 vs IP69K: Which One Does Your Facility Actually Need?

This is the question most buyers get wrong, so it's worth being precise. The two digits are not cumulative in the way most people assume. A rating of IP67 certifies immersion performance - it does not, on its own, certify resistance to high-pressure jets, which is what digits 5, 6 and 9K cover. A light can pass an immersion test and still let water past a gasket when a sanitation crew hits it with a 1,200 PSI wand at close range. If your plant does high-pressure or steam wash-downs, you want a product tested to both an immersion rating and a jet rating (often written as "IP67 / IP69K").

For the overwhelming majority of North American warehouses, IP67 is the correct specification. It covers every realistic water event short of a daily steam clean, without paying for over-engineering you'll never use. Our safety spot lights and safety zone lights are built to that standard precisely because it's the level real facilities need.

When Would I Need Forklift Lights That Are Waterproof?

You may not think of many instances where your forklift lights will have a chance of failing because of water, but depending on your location and weather conditions, forklift lights may be likely to be prone to water than you think.

If your warehouse has large, open water or liquid tanks, you'll never know if there will ever be a possibility in which a forklift will drive by one of these tanks and a light will fall right in one. If your forklift also operates outdoors, rain can also be a problem over time, despite the fact that you might not think that much water comes down onto your forklift lights. Also, in case of a flood, you might be able to salvage your forklift lights so that's one less expense afterwards.

Seven US Environments Where IP67 Pays for Itself

1. Cold storage and freezer warehousing

Frost, defrost cycles and constant condensation are brutal on unsealed electronics. Sealed IP67 housings stop moisture from migrating inside during temperature swings.

2. Food and beverage processing

Daily sanitation, standing water, drains and food-safe chemicals. Look for IP67 as a minimum and IP69K where pressure washing is routine.

3. Outdoor lumber yards, nurseries and building-supply yards

Rain, snow, road salt and UV exposure year-round, from the Pacific Northwest to the Gulf Coast.

4. Port, rail and intermodal terminals

Salt air accelerates corrosion around every seam, connector and fastener.

5. Recycling, waste transfer and composting

Wet loads, slurry, and dust so fine it behaves like liquid - this is where the "6" matters as much as the "7."

6. Hurricane- and flood-prone regions

Gulf Coast, Southeast and Midwest river corridors. As the original article notes, salvageable lighting after a flood event is real money recovered.

7. Loading docks and trailer interiors

Rain blows straight into open dock doors, and trailer floors stay wet for hours. Forklift work lights get the worst of it because they're mounted where the weather is.

Does an IP67 Rating Make a Forklift OSHA-Compliant?

No - and this is an important distinction, because a lot of content online blurs the two. An IP rating is an ingress protection standard, not a workplace safety regulation. The two intersect but are governed separately.

In the United States, OSHA's powered industrial truck standard (29 CFR 1910.178) addresses truck lighting in terms of illumination levels: lights must be provided on trucks where general lighting is less than two lumens per square foot. There is no OSHA clause that specifies an IP rating.

Where the two connect is reliability. A blue spot light or red zone light only protects pedestrians if it's actually working. A water-damaged light that fails mid-shift is a safety control that has silently switched itself off - and nobody notices until an incident. Choosing IP67 is how you make sure your pedestrian-warning system is still functioning on day 800, not just on day one. For broader guidance on building out that system, our forklift safety tips guide covers the operational side.

How to Verify an IP67 Claim Before You Buy

Anyone can print "IP67" on a box. Here's how to separate tested products from hopeful ones:

• Ask which standard it was tested to

The answer should be IEC 60529. If the supplier can't name it, that's your answer.

• Ask whether the assembly was tested, or just the housing

Water gets in through cable glands and connectors, not through moulded plastic.

• Check for potted electronics

Encapsulating the driver in resin means that even a compromised seal doesn't kill the light immediately.

• Look for a pressure-equalizing vent membrane

Sealed enclosures that can't breathe build internal pressure differentials during thermal cycling - and that is what pulls moisture past gaskets.

• Confirm the lens material and gasket compound

Polycarbonate with UV stabilization for outdoor use; silicone rather than cheap rubber for chemical resistance.

• Read the warranty terms

A manufacturer that genuinely tests to IP67 will back it. Water ingress excluded from the warranty is a red flag on a "waterproof" product.

• Ask about the operating temperature range

IP67 is meaningless if the light can't handle −30 °F in a freezer aisle.

Which BEAST Lights Are Built for Wet and Dusty Environments?

Every product family below is engineered for the same sealed, industrial-duty standard - the choice comes down to what warning function you need, not how waterproof it is:

• Safety spot lights - the classic blue (or red) projected spot that warns pedestrians at blind corners and aisle ends.
• Safety arc lights - a bright red line projected to the side, creating a visible keep-out boundary along the truck.
• Safety zone lights - full perimeter zone marking for high-traffic pedestrian areas.
• RZR kits - 4 lights in 1 - combined warning functions from a single sealed housing, which also means fewer penetration points for water.
• Safety strobes - high-visibility flashing warning for shared-traffic and outdoor yard operations.
• Forklift work lights - task illumination for trailers, dark aisles and outdoor night shifts.

If you're weighing LED against older halogen or incandescent units, our breakdown of the advantages of LED forklift lights explains why sealed LED housings hold up so much better in wet environments in the first place - there's no filament, far less heat cycling, and no bulb-change access panel to leak through.

Frequently Asked Questions About IP67 Forklift Lights

Is IP67 fully waterproof? 

IP67 is water-resistant to a defined, tested level: full dust protection plus immersion in up to 1 metre of water for 30 minutes. It is not rated for permanent underwater use, and on its own it does not certify resistance to high-pressure jets.

What's the difference between IP67 and IP68? 

IP68 covers continuous immersion deeper than 1 metre, with the exact depth and duration specified by the manufacturer. IP67 covers a defined 1 m / 30-minute test. For forklifts, IP67 is almost always sufficient.

Can I pressure wash an IP67 forklift light? 

Not safely at close range or high pressure. Immersion protection and jet protection are tested separately. For routine pressure washing or steam cleaning, specify a light that also carries a jet rating such as IP69K, and keep the wand at a distance.

Do IP67 lights work in freezer and cold storage applications? 

Yes, provided the product's operating temperature range covers your environment. The dust-tight seal is actually a bigger advantage in cold storage than in wet areas, because it blocks the condensation that forms during defrost and dock transitions.

Does OSHA require waterproof forklift lights? 

No. OSHA regulates truck lighting in terms of illumination where general lighting falls below two lumens per square foot. IP ratings are an equipment durability standard, not a regulatory requirement - but a light that fails from water damage is a safety control that stops protecting anyone.

How long do IP67 forklift lights last? 

Sealed LED units in normal warehouse duty commonly run for tens of thousands of hours. The realistic life-limiting factors are vibration, connector corrosion and physical impact, not the LEDs themselves.

Does an IP67 rating stop dust as well as water? 

Yes - the "6" is the highest solids rating there is, meaning fully dust-tight. In flour mills, cement plants, recycling facilities and grain handling, that first digit often matters more than the second.

Are blue spot lights and zone lights available with IP67 protection? 

Yes. Sealed construction is standard across the BEAST warning-light range, including spot, arc, zone and strobe products.
