altima

A couple of days ago, my low beam headlight on my Altima went out for the third time in a year and a half. I'm thinking there might be a ground somewhere in the wiring, any opinions? Also, how much would I have to pay to get this fixed? I work on my own cars but I don't know shit about wiring.

I have just put in new struts on my Altima, It didn't come with chamber adjustment bolts. I have almost a whole degree of positive chamber on both sides, how long does it take for the new struts to settle?
