Halogens require a (nominal) 12V voltage source and operate like any incandescent light. LED's require a specified amount of current to operate. HID's require a ballast to ignite/start.
Thanks for the clarification. It looked similar to the ballast in another car I owned with HID headlights.
I guess now I understand why people say that the high beams are not that great. It is not connected to the voltage regulator, so I assume it is a halogen bulb?
I did more investigating inside of the LED headlight and found several additional wires inside that did not appear to connect to a harness or a bulb.
I removed the 3 screws holding the regulator in and discovered wires coming out of the back. These went to the smaller (lower) bulb LED and also appeared to attach to a internal component with a large heat sink.
So the 4 wires connected to the top of the regulator are most likely ground and power. And those out the bottom are the regulated current that feed the LED bulb.
