Left head light turns off occasionally

[s4BoostKing]

Randomly some nights my left headlight will turn off sometimes blinking first. But if I turn the headlights off then back on they both come on fine for a while the then left one will go back out. And sometimes it will go away for a few days then come back. Also the bottom rear tabs are broke off both taillights so they jiggle a little bit at high speeds. I replaced the bulb the other day but the problem is still here. Any ideas?

Loose connection, ballast going out? You can try swapping your ballast over to see if, the other headlight will flicker or go out.

I'd likely try to repair those tabs so the headlight isn't shaking around all the time. Could be a corroded connection or a ballast. Though usually when it's a ballast they either work or they don't.
