I have a 2014 chevy silverado. Bought the plug and play lights the GX series. Installation is super easy. I did have to unplug and plug them in 2 separate times for the connection to read right though. Other than that no problems. Now are they bright? Um... they are basically light bars! They light up both sides of the road and the ditch bank. My corn field is 60 ac long. I can light up the whole field! I'm 100 percent impressed with these lights. I will be buying these again. There is one downside. Other drivers will bright you 24/7, but I have a lifted truck and it doesn't bother me. But the other people are seeing Jesus! Pictures do not do these lights justice.. they are BRIGHT. Don't second guess buying these.
