Just thought I'd give an update on the situation:
Turns out it was the bulbs lol. I spent about an hour switching the ballasts and the problem stayed on their sides (Flickering on the left, sometimes doesn't turn on for the right). I was too lazy to take them all out and try switching the ignitor, so I thought why not, and switched the bulbs. The problems stayed with the bulbs and the left one started to sometimes not turn on. Just a reminder for anyone that doesn't want to waste an hour, and if you're like me, lose a screw into the engine bay.
