Is that the only way you can discribe them?
My 02 with stock lamps are fine.
If you need to spread flames at nite then you do have a problem or there is a ground problem on high beams. Both extremes.
The lamp housings are lexon and can become clouded in older trucks then they need polishing.
Better discribe what you think your situation is.

They are just not that bright to me. My cars highbeams light up the road but they f150s are just a tad brighter than the low beams.

Here is my position.
Some times it is a subjective outlook as to what is bright.
Some people want to throw flames all over the place to make it look cool and draw attention in addition to blinding others.
Here is what I would do as check out.
Measure the voltage on low beams at the lamps with the engine running, then on high beams.
If the voltage is more than about a volt lower on high beams then suspect a ground to be bad or some other part of the headlite circuit. I reality the low beams would be down on brightness also if there is excessive voltage drop, just that you can't judge that. The only difference is the current flowing thru the same ground or defect.
On the other hand, the housings have to be adjusted high enough for projection out to at least 100 yards on high beams.
On the other hand again, these housings are Lexon and not quite as good as sealed beams or clear lenses with silvered reflectors like many other trucks.
If you don't find a circuit problem then replace with lamps about 20% brighter than stock to satify yourself without going overboard on brightness and current draw. But do the testing and correct for problems before going to higher power lamps.
IMO headlite brighness has never been a big issue with these trucks for the average owner.
I do a lot of nite driving and tow as well and there has never been an issue with lighting on stock lamps.

Maybe this is a problem for 2004 and up F150s? I am 34 years old so I guess my vision is noit what it once was but my GFs car and my GXP have brighter high beams.
No I dont want to blind people but I do want to see better.

I'm glad no one is taking offense at this discussuion on perspective of lighting.
The new trucks should be better than all up to 03.
All I was referring to are the lighting changes that people make and become accustom too when compairing back to stock lighting.
I have no way of knowing why anyone has a problem with stock lighting except for off roading applications and other reasons outside of the federal standards that exist and are designed to.
So you can see that your inital comment about your lighting was not at all informitive as far as what answer to offer you until some of the facts and reasons are made known.
If lighting standards are investigated, one would fine a large list of specs the headlites are suposed to adhere to for aiming, focusing, horizontal and vertical beam spreds etc that often bar lights cannot meet..
When using aftermarket lighting I would say that almost none are really legal (for legal road use) except on lamp replacments where the wattage has been speced within original guidelines.
So you do what you have to do. and BTW I am far past 35.

Does anyone have any problems with highbeams not working completely? I can hear the "flickering" coming from the fuse box, and have changed the fuse, but still no luck. Any suggestions??? I need to take the truck to the dealer but its hard to spare my truck for the day.

i agree with the poster above...the high beams on my '05 SCrew are definitely an upgrade over the ones on my '03 SCrew.
but neither of them beat my wife's explorer high beams...man those things are awesome. they have the same light set up as our trucks, but instead of the turn signal on our trucks, the explorers have a high beam type driving light. man those suckers are BRIGHT!

May be the headlites are aimed to high such that hi beams are to far into the nite air.
I have different housings on my 02 and hardly anyone ever flashes me even on hi beams. Same with my Lincoln.
On the truck I have the aim favoring the right side and a little high so I can see the side and banks well for deer but still light up the road well enough.
This helps not getting to the oncoming drivers unless going around a righ hand curve then it's prudent to go low beams.
