IP Ratings Explained

IP Ratings are an indicator of product quality. If a product’s IP Rating isn’t disclosed, it’s probably for a reason. It is also important to consider the validity of the IP Rating advertised.

All NightRider LEDS Light Bars and Driving Lights are rated IP67, and Heavy Duty Lights are rated IP69K. NightRider is a Canadian company that has been providing LED Lights from coast to coast and has earned their reputation for delivery high quality LEDS.

What is an IP Rating?

An IP Rating also known as Ingress Protection are standardized ways to measure the sealing effectiveness of electrical enclosures against intrusion from foreign bodies and moisture.

Why do IP Ratings exist?

IP Ratings provide a standardized and defined measure of a products sealing effectiveness. For example, terms such as ‘waterproof’ and ‘water resistant’ can be vague and differ greatly between different products and companies.

How to read IP Ratings

All IP ratings begin with IP and are following by 2 digits, and an optional 3rd letter for other protections.

First Digit – the first digit measures the intrusion protection of solid foreign bodies (such as dust).

Second Digit – the second digit measures the intrusion protection of moisture and liquids (water).  

For example, the rating IP67 translates to the following:

First Digit: 6 – dust tight, no intrusion of dust

Second Digit: 7 – immersion in water up to 1m depth

IP Rating Reference Chart Summary

First Digit – Protection Against Solid Foreign Bodies


Effective against (object diameter)




No special protection against contact or intrusion of objects


>50 mm

Protection against larger parts of the body such as a hand


>12.5 mm

Protection against items such as fingers


>2.5 mm

Protection from items such as tools, large wires


>1 mm

Protected against intrusion of most wires, screws


Dust protected

Dust intrusion is not entirely prevented, but cannot intrude in sufficient quantities to interfere with the operation of the equipment


Dust tight

No intrusion of dust, complete protection against dust contact


Second Digit – Protection Against Moisture


Effective against




No protection against liquids


Dripping water

Protection against vertical dripping water when the enclosure is upright


Dripping water when tilted at 15°

Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position


Spraying water

Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect


Splashing water

Water splashing against the enclosure from any direction shall have no harmful effect


Water jets

Water projected by a nozzle against enclosure from any direction shall have no harmful effects


Powerful water jets

Water projected in powerful jets against the enclosure from any direction shall have no harmful effects


Immersion, up to 1m depth

Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion)


Immersion, > 1m depth

The equipment is suitable for prolonged immersion in water


Powerful high temp. water jets

Protected against close-range high pressure, high temperature spray downs
