I purchased my G two weeks ago during the day time from a private seller, headlights both worked and were on when I looked at it so I didn't give it much though. 2 weeks later I am driving at night only to find out that my low beams, NOT fog or high beams, flicker when I turn them on and off and when I hit slight bumps in the road they turn off/flicker. After all the reading I've done I thought it may be the ballasts or the bulbs themselves but I'm starting to doubt that both the ballasts or bulbs are dying since both of the headlights are going out simultaneously. However, sometimes the right one will stay on and the left will turn off and vice versa when I'm sitting there turning the lights on and off or driving smoothly. I'm honestly clueless on what the problem is.. maybe the wiring harness? Or should I just suck it up and buy new bulbs and ballasts? Any help is appreciated!

Monitor your voltage at idle. Maybe you have a faulty alternator?

With a almost seventeen year old vehicle if the bulbs and ballasts are original OEM and the alternator is putting out 14.4v then it is highly likely that you need to replace both bulbs and ballasts

So I went under the fender covers and realized that the headlights installed are Eagle Eye headlights.. However it looks like the previous owner tried to splice in the new headlights with the old connectors? I'm thinking about just going ahead and buying a whole brand new headlight assembly.

eBay has some $200 reflectors that work pretty okay. Great price for the light. Don't buy the faux projector ones.

I've looked around a bit and every pair of headlights that are around the $200 price range seem to be the Halogen models that say they won't work for xenon HID models? How come they aren't compatible even though they come with a ballast and a 6000k HID bulb?
