I am not sure if that is "Amazing Production Quality Control" that both go out within minutes of each other, or if that is a real problem somewhere.
Once I put LEDs in, there was no more of that nonsense.
Cheers,

Note that I did not say "within minutes." It can be hours or days because if you are riding alone you might not know one of them is out. I replaced lots of low-beams in my Wing (never replaced a high beam bulb). I also run LEDs in my F6B.
