LED Headlights installed..

Im trying HID's in my Barracuda...Im also using an aftermarket "crystal" style headlight with clear flat face...Low beam is mint...High beam is all over the place, and Im tipping its the position of the source on the HID bulb...looking for an alternative now, been reading this thread with interest...I enjoy the actual white light Im getting now, but HID's are illegal in Australia for a start, without auto dimmers....The LED bulb assemblies look attractive as its an easy ( and cheap) swap, but am reading mixed results...
