2005 Chrysler crossfire low beam light fuse/bulb are good, still does not come on..What may be problem?

one or both? I lost a low beam. I simply replaced the bulb. they can go intermittently so I say it is simply the bulb. Yeah, I was all worried it was the wiring, a ground, a major electrical problem. No. Just a bulb. f you do it yourself, do not touch the bulb with fingers because the oil will heat up the bulb and decrease it's life. Sounds preposterous but it is true.
