I just did the Walmart burner rock light install today. I think they look great. I took pics but cant upload them until tomorrow. I ran 4, two attached to the bolt in front of the front tire wells ans the other two in the last bolt hole under the jeep where the stock running boards attach, those need a 8x1.25 metric bolt. All of those are connected to a 30A relay and then to an LED switch I mounted on the drivers A pillar. Install was a pain but I took my time to hide every wire. As far as function, I know they will be used offload and make a diff. As far as looks, they are really cool. Total cost was probably $75. LEDs would have been a little more but I'm going to buy an sPod soon and will run to that. I say go for it if you will ever find yourself offload in limited light situations.
