I do a lot of night driving (8-10 hours a day) and once I get the headlamp size figured out, putting Hella E-codes on my M1009 will be the first thing I add on this summer. I had a '09 Jeep and the headlights totally sucked on that, how I drove it at night I have no idea. What I did was get Hella E-code headlamps and an upgraded harness and you wouldn't believe the difference it made.
The main factor in why these lights work so good is because the light is focused much better and the cut off is much better too keeping the light on the road where you need it, because the cutoff is so sharp you can aim the lights higher too without blinding anyone. Even without upgrading the bulb wattage from 60/55w the E-codes will do you good.
Now I should say that it was 7" round headlamps and I did have an upgraded wiring harness to run the lights on, but if you got an upgraded harness and the rectangular E-code headlamps I think you could expect close to the same as with the round headlamps. I think this is the type you'd be looking at
Susquehanna MotorSports - Auto Performance Product that place also has kits,but not sure if it's the same lamp.
Edit, if you look at that kit from Susquehanna, you can get 100/80w bulbs.
