Rigid Industries' E-series cover offers both style and function to give the perfect solution. It not only protects your vehicle but at the same time it offers it a unique look. The covers have been made from polycarbonate plastic that is durable and gives another layer of protection to the lens of the E-series LED light. It is easy to swap the covers since they snap on and off making them very convinient for the user. If you are in a state that requires covers for accessory lights we recommend the E series covers. They come in segments of 10 inches meaning if your E-series LED light Bar is 30 inches you will only need three segments each 10 inches.
