The IP rating is an important consideration for determining the resistance and durability of the product. As you are going to mount the LED light bar on the exteriors, it’s important to select a material with equal to or above IP67 rating. The higher the IP rating of the light, the more it lasts. Basically, IP rating suggests the weather and dust resistant qualities of the product. You will find better options featuring up to IP69 ratings, but that can turn out to be a bit expensive for budget buyers. If quality is your main concern, then consider the IP67 and above the LED light bar for your car. This rating also guarantees that the lights will not be damaged even if they are submerged in the water.
