The biggest problem I had with lighting was the beam pattern; the standard headlights don't seem to throw much light to the sides, and they have a very bright center spot. I prefer the more even lighting that my Ranger had. But, the beam pattern is a function of the lens assembly, so that can't easily be changed.
I have the PIAA 9007 Superwhites, 55/65 watt (even though Performance Products calls them 55/60 watt) which are supposed to be as bright as 100/110 watt bulbs. I don't know if that is the case, but they are definately considerably brighter than the standard halogens, and whiter. I'm still experimenting a bit with the beam adjustment, but so far I really like them.
I also have some Pilot driving lights. They aren't pencil beam, but they still shoot down the road pretty far. They work very well with my high beams, filling in the gaps and providing plenty of light on the side of the road. I have them wired to go on with the high beams only, so that I don't have to turn two switches off when traffic approaches. It was kind of difficult finding a place to put driving lights, since I already have the factory fogs (which are pretty good IMHO) in their respective spots. That's why I chose the pilots.
Here's a picture of the front of my Explorer. You can see how the Pilot lights fit in the lower air intake in the bumper. I don't know how your bumper is shaped exactly, but I had no other choice on mine:
I will add that the Pilots are a bit cheap, but they use industry standard H-3 bulbs and are easy to install. I don't know if PIAA makes a light small enough to put there or not.
