so i cleared my headlights about a year ago and this past weekend it started pouring and now my right headlight doesnt work :( its only my lowbeam, everything else is good...can anyone help me out? should i just replace the bulb or wut do u think it is...any input would help. thanks

Common problem, its the ballast. There is water in it.

You need to open the lamps up again, drain the water out, reseal them properly, and then bake the ballast for 30 mins in the oven at 230 degrees.

Sounds work fine then, but it will happen again if you dont seal them right..
