Left Low Beam Malfunction

[Unit107]

So I get this done and everything is working fine...

And now, about a week ago, my right headlight goes out. Same warning message indicating Right Low Beam failure.

Why my dilemma is interesting, is that when the left one failed, I swapped bulbs to see if it was the bulb or the ballast. Since the left bulb was working in the right side (right not working in left, but did once ballast was replaced), I left it there and went to work on ordering the ballast. Fast forward two months, and the right side fails.

I am curious if there might be an issue with the bulb that could be causing the ballast failure, or if I am truly lucky enough to have a double ballast failure in less than 2 months.

Before going completely dead, the bulb was giving off a dim pink glow. This was for about 3 or 4 starts, then it was dead with the warning message.

Again, I had a 2001 X5 with Xenons for 13 years and NEVER had an issue with the headlights. It seems strange I would have both go within months of each other on a 6 y.o. vehicle.

Any thoughts on whether it is the bulb could be causing a ballast failure, or just dumb luck? or if I should avoid the swap-back of the bulb to avoid frying the new ballast I just put in on the left, if the bulb is causing the failure(s).?

Thanks,

Mark
