Intermittent Headlight On/Off

Intermittent Headlight On/Off
Installed my 2012 headlights. My drivers side headlight worked when I tested prior to putting bumper back on. I was driving around last night and the light went out. Stopped for gas, start the car back up and the headlight works again. About 60 seconds later, the headlight went out again. I recycled the light switch and it worked, but then went out about 60 seconds later again. Should I swap the ballasts out first or the bulb out first? I feel like the bulb is not the issue considering it works still when I recycle my lights.
EDIT: All other functions of headlight operating normally.

Wanted to bump this thread to see if anyone else had experienced this... my passenger light started doing this the other day. I noticed it was off, and the next time I started the car it was back on, but about a minute later it was back off. This time I just turned the switch to off, and then back on a few seconds later. Same thing. Bulb worked for a minute or less, then went back out.
I am hoping it is just time for a new bulb, but I haven't had time to troubleshoot yet.

Almost always bulbs. The confusing thing is cycling the lights brings it back, but when you replace the faulty bulb, BOOM, no more issues.

Had this happen a hand full of times with the driver side light after i installed my 2013 lights. Before doing anything crazy, i swapped the bulb to the other side to see if the problem switched sides, and i havent had it happen again...

It's part of the voltage system. If you disconnect a bulb while powered you'll notice the same result when you plug it back in. Power cycling the lights resets the circuit.

That doesn't make sense. Maybe its only because I've been working with electronic devices at the component repair level for about 40 years, but disconnecting the bulb while it is powered doesn't strike me as a great idea for maintaining a long service life on the inverter. Disconnecting only resets the arc striking phase of operation, the same as power cycling, except power cycling allows the inverter to stabilize before it gets loaded. Sure it's only a few milliseconds, but anytime you are multiplying voltage you're far better off giving the device a moment to collect itself before subjecting it to load. JMHO.
