So on the way home last night in my car, my gf hits a pothole, it felt pretty rough, but everything was fine About 5 min more down the road, my low beams and fogs (all HIDs) are pulsating rapidly and my head unit screen goes blank. The car continues to run fine and all other instrument lighting works fine. What could this be and why only the headlights and my head unit? Help?

 

anything shorted? trace ur wires for the HID and HU?
