I think they screw up the wiring
review below
Very bright!
I like everything about this light except the power cord connection to driver...after a solid month of performance it won't stay connected,this is horrible because I tried to tape it and now it won't connect at all...think it's melted on the inside the connection going to try and get this fixed hopefully mars sends me replacement update I tried getting a replacement but mars trying to have me download a video and fix myself deff not happy if it worked this would be 5 stars
