The glass bubble is a projector. For these headlights, they are designed for halogen bulbs. The OP retrofitted them with HID projectors which you see on most luxury cars.
Those are the low beams, the inside are the high beams. I have mine set to have low and high beams on at the same time but you have to open the steering wheel column and add a wire there to do it. This is safe to do in these headlights without a meltdown. Halos get spliced into the parking/running lights using a quick splice that can be found at radioshack or elsewhere. Turn signals still work the same. The turn signal harness has 3 wires. One for ground, one for turn signal, and the other for running/parking.
