Hi all, I am over in Australia with a converted AT4 so there are no dealers or colleagues to seek advice from so apologies in advance if I am missing something obvious.. I have Google extensively bulb upgrade for my high beams as they are pathetic on country roads. The very limited information I can find suggests to me there are very limited options. They appear not to be HID bulbs? I can see limited options if they were HIDs. Any advice/options/part numbers for what I suspect are LED bulbs please? I have also researched a behind grill light bar but this is also troublesome with the active grill shutter. Thanks in advance. Dane
