So last month was blown ballast month here...I replaced my ballast and ignitor last week, and my light started to work fine. Now exactly 7 days later, I go to leave for the night Friday, and my light is out again....

Im thinking either the entire housing unit I need to change now, or somethin...

 

if you had a bad ballast and didnt replace the bulbs you are asking for trouble
all that funky voltage is BAD for them
There is an area on the housing that benefits from silicone seal too

 

The bulb still does the same thing it was doing before, when I turn it on, it flickers like it wants to turn on, then goes out. You think it might just be the bulb?

 

just bought a brand new headlight lamp lens and housing

 

try swap the bulb with the other one.
if still do the same it's mean you have bad ballats.
sometimes new not always good. (defects)

 

Its funny I turned the lights on last night and the light came on for like 10 minutes, then blinked out while driving. To be safe Im gonna buy some replacement bulbs

 

Always buy the bulb as a pair not just one.
So, they're match.
And also always buy a new one.
Cuz you never know how the bulbs were handle before, and have warranty on the new one.
Ebay sometimes have a good deal on bulbs.
