That should say Totally Integrated Power Module aka TIPM. It is the fuse box, but in your case it is a lot more than just a fuse box, it controls pretty much every electrical component on the car, and they are a very well known failure item. In your center picture it is the black box next to the fender. It has a circuit board inside it with all the relays and controls for the electronics on it. To repair them, you replace the entire box or you can send them out for repair.
First however you will want to verify that the ground is good as it can corrode off and you lose the light, especially as you lost both high and low. An easy way to verify it would be to remove the connector from the bulb, use a test light connected to ground (battery negative) turn on the lights on either beam. Now probe the three wires, the light should come on when you touch either pin 1 or 3, switch to the other beam and check again, it should now light on one of those two, but the opposite of the first time. Now connect the light to battery positive and touch the light to the last terminal 2, if the light doesn't light the ground is bad. There are a couple ways to deal with this, the correct way is to follow the wire over to the ground connection and repair it as needed. The other way would be to splice a new wire into the existing and attach it to a different ground point.
If there is no power at either of the two (1&3) pins in either headlight position then it is likely a bad TIPM. There are ways to wire in other relays to bypass the internals, but the testing needs to be done first, and then you need to decide.
