The lights are expensive but you get what you pay for. They are extremely bright and appear to be quality built. I've only had them on for a few days, but man are they nice. They come in a box with includes a wiring kit and switch. The directions are crap, but they are pretty easy to install as the wiring kit is already set up. One issue I had was hooking the switch up. The ground (black) goes to the gold looking connector, the blue wire (power) goes to the middle connector, and the red (positive) goes to the far connector (not gold looking). If that makes me seem like a moron, you're probably right, but I hope it helps.
