There are no instructions in the kit, there are 5-6 pieces but I'm not sure where it goes. Looks like you're about to turn on your headlights. I have no good feeling about how long they will stay. There is USB, but there is no connector for the plug. The headlights work well. I would say the photos are not pointing you in the right direction.
