I was driving down the road last night and I flicked my high beams on and suddenly my high and dipped beams (HIDs) all turned off (side lights stayed on) I immediately pooed myself and turned the lights off and on again and my dipped beams came back on however my high beam bulbs had both blown. Then later on, driving home my dipped beams started to flicker and every so often would turn off for a second then turn back on again. Then they started turning off for longer, or would not turn themselves back on and I would have to keep turning my lights on and off again until they came back on. Now when they turn off I have to turn the ignition off and on again for them to turn back on. Also I have found that if they cut out and turn the ignition off and then on again they will turn on, but then when I start the engine they will turn off again but will eventually stay on. Its all very temperamental and there doesn't seem to be anything causing it, it doesn't happen when I hit bumps or anything, just randomly. Anyone got any advice?
Sorry for the essay, just want to give as much detail as possible.

my advice would be not to drive at night untill its sorted. Where are you located? a good auto electrician will rectify the shoddy, dangrous work done to your car.
What HID system is fitted? any pics of the units (not the lamps or housing, the balast units) wiring and any relays or other units associated with the aftermarket lighting system.

If what the OP says is accurate, I think the clue here may be the blown main beams.
There's no connection at all between the dipped beams and main beam power circuits, other than the common earth point, and the common power feed to the fusebox, and faults with either of these would not blow bulbs.
I think you should be investigating the alternator, and possibly the battery and its connections. Start by measuring the voltage across the battery terminals with the engine running.
