Corner light help

[jd123]

Ok, I installed some new clear heads and fogs on my 00 F150. When i turn my heads or corner lights on only the driver side corner light lights up. But if I turn on my flashers or right turn signal it works? Is it a loose connection or what?

It's a dual filament bulb, most likely, only the flashing filament is good. Try a new bulb.

I just went and looked, and it appears that one of the filaments is gone bad. So, I'm almost positive that's my problem.
