In city driving, I agree the lighting is sub-par. OEM casts such a large unfocused beam it blends with street lighting, but most city lighting is enough. On the open highway between civilization, I find the OEM lighting does the job. Click your brights on and be mindful of oncoming traffic, it throws plenty of light in the dead of night.
Alternatively, the only other way to get more light is to dive into the aftermarket. There is an outfit that does custom HID projector retrofits for many vehicles including our late model F250+. They run about $1200 a set. With this outfit, you really get what you pay for. If you're a DIY person, you can save about 60% on that price tag, and buy the projector kit and retrofit your own headlamps, but you better be sure you know what you're doing, any mistake could put you in for buying another set of headlamps, and then you won't feel so thrifty.
OEM headlamps suck, there's no fighting it. Spend $30-$50 on bulbs all you want, the results will be pitifully minimal at best, if not make it worse. Go projector or suck it up and deal with what OEM gives ya. There's no shortcuts in proper light output. Don't be that guy that makes halogen reflectors so bright he blinds everyone else... bad things happen to those people and their rigs.
