if you're looking for distance I would prioritize the lights located higher up on the truck.
For general lighting the bumper mounts work well.
I have done after market lighting in 2 F250s for long haul driving and lighting on my raptor for use as a hunt truck.. this is what i found and did:
On each of the F250s, I added a 20" combo light bar in the bumper tied into the high beams. The light bar has a spot beam in the middle and floods on each side. In addition I have a rigid dually D2 with a driving beam in each of the fog light pockets switched on the factory fog light switch. I can add amber covers if needed. This work very well for my highway/long trip driving needs.
On my raptor, i have the following: 30" combo in an ADD bumper tied into my high beams. 2x 4" Rigid SR spot lights with amber covers in the front bumper, 2x 6" rigid SR spots facing on angles to the right and left in the front bumper as well. I have a 50" forward facing flood light bar on the top of a chase rack and a 30" rear facing flood light bar on the chase rack as well. I have several dually D2 diffuse lights on the sides and rear of the truck. I use this set up for staging my hunts in the dark with a bunch of people, dogs, boats, ATVs and gear. the 30" is great for highway driving and the 4" ambers are a good contrast in fog or misty mornings.
For me, I was able to do it all at once, if i had financial or time restrictions, I would have prioritized the forward 50 and rear 30.
there are a lot of great lighting manufacturers on this forum and around. figure out what YOUR need is and then gather data and make you're decision. I got a lot of direction from dealers and manufacturers that meant well but wasn't accurate for my needs so I had to step back and figure my plan out, then find the right type of light and then the company with good products service. I'm very satisfied with the outcome of my set up.
hope this helps..
good luck!
