Another huge benefit of LED lights is their extremely rugged nature. The Rigid Industries E-Series light bar features an unbreakable and scratch-resistance lens that sits in a tough aluminum housing. They are also IP68-certified, making them impervious to dust and water. On top of this, there is no traditional filament to worry about breaking. Another benefit of light bars, such as the E-Series, that is often not discussed is that their low profile design allows for more air to enter the grill area when front mounted and less drag when roof mounted.
