Last week my passnger side Xenon lowbeam went out. I order new ones and tonight after installing the new bulb, it still would not turn on.

Could this be a bad ballast? And is replacing the ballast an easy DIY?

I did notice while driving the past week with just the driver side lowbeam that it had a tendency to flicker on and off. Not sure if the 2 issues are related, but I have a feeling ti may be since the new bulb didnt light up.

Any ideas?
