And the lights are Hella 500s. Just like most everyone else has on their trucks. The only difference is that I put some HID lights in mine.
But as a basic little way to explain it...
Open up the back as if you were going to put in the 100 watt bulbs, or whichever. Then the tab that holds the bulb in, pop it out. Now, the back side of the housing has a hole for the wires, with a little plastic deal to keep the water out. Pop that piece out, then pull the wires out. This hole will be too small to pull your HID wires through, so you need to take a little file to it. This housing is so easy to file, you could do it with a finger nail file. Slide the wires through the back side, then pop the cap off your HID bulb, put it in the glass, then put the housing on. There is just enough room that the bulb is held in, but it won't move. So don't worry about there not being anything to hold the bulb. Then from there, you just hook the up the ballasts to the lights. Now the thing that will get you, I think the blue is positive, and black is negative. Whichever they are, I had to reverse them on my lights.
Oh, and don't forget that you also need to take some black silicon to the backside of the housing where you had to file the hole. I just used some black RTV, and I haven't gotten any water in them, and it's raining now, and I've also washed it once.
