Auxbeam FTW
Color: 4inch Flood Light, Color: 4inch Flood Light
Quality product at an affordable price. The pods have a good weight to them and the bracket feels sturdy. I don't recommend them if you're looking for a true yellow light, those covers suck . The drl and turn signal feature is really nice 👌🏼. Only bad thing i can say is that the hardware is starting to rust but thats an easy fix .

cheaper solution but not cheaper in build and functional quality
Color: 4.5inch Spot Light
Im normally a Rigid guy but these Auxbeam LED Pods are brighter than my Rigid. They from my opinion are at the same build quality as the main name brands but at 1/2 the cost..
