I live in probably the most desolate area in the country, if they show a night shot of the US, the darkest area is the great basin, (mid to north nevada) so IT IS DARK AT NIGHT HERE, so any improvement in lighting is very evident, I have driven state hwy 93 from Wells,NV, to Vegas (500+ miles) and have seen as few as2(!!!!!) vehicles this was christmas eve 2009, most of the time I run my "old" 130 watt KC's no longer available, the most power you can find is the 100 watt, The reason for this long, sad tale is to show that I have some experiance with the inadequate lights on these trucks,since thes are all I have driven for the last 11 years between Vegas and Elko (2 trips a week, 1 down and 1 back ) I think I have found ALL the weak points, or attacked them before they became disasters thanks to YOU MEMBERS, now I'm trying to give back what I can, and this is an area I think I have done the most experimenting with for the $, my suggestion,I think, works best, however, there are brighter lights (HID) the price and install headaches are too high for my tastes. my wifes grand cherokee has 'em and they ARE brighter than my setup, but they came with the car, and they are NOT brighter than my KC 130's, so I hope I helped
