Ok, I'll just shout out some pretty generic RBV lighting tips...
I have a gen 2 Bronco II, so I don't have the same housings as you, but all of this really applies...
1. Make sure your lenses are not yellowed, and your reflectors are still shiny. I'm talking mirror like shine, not just "Yea they're still silver." If the just the lenses have yellowed, you can buy polish at advance, autozone, etc, that will buff them clear. This helps, but the inside of the lens yellows too, and you can't polish that, so there's only so much good you can do...
2. If your headlight housings are too far gone, buy some new housings. Ebay is your friend here! I picked up a set of headlights for my Bronco II on eBay, and they cost me like 60 bucks shipped.
3. If your truck doesn't already have them (I believe your truck should, because its a later model) convert from 9006 bulbs to 9007 bulbs. You can look it up on the forums, as its a simple conversion. You have to shave one locating pin out of the headlight with a knife, and then swap two wires... I believe I did a writeup for us 2nd gen ranger and BII, and 1st gen explorer people, and you should be able to find that on here...
4. Buy Silverstar Ultras, or a pair of the Phillips ultra white bulbs. Silverstars can be found locally, the Phillips bulbs usually have to be purchased on the internet.
5. Make sure your headlights are aimed properly. Too low, and you'll just illuminate the road directly in front of you. Too high, and you'll be blinding other drivers, and you still won't be illuminating the road properly.
6. If all the above fails to make you happy, its time for auxilarly lighting. If you want to see way out in the distance, get yourself a decent pair of driving lights, such as Hella 500's, 700's, or 700ff's. You can search the forum to find out more about all that stuff if you need more info.
By all means, do NOT install one of those aftermarket HID kits in your lights. They blind the crap out of other drivers (even worse than improperly aimed headlights) and really they aren't going to do that much for you, because the beam won't be focused properly. But really, the above list of things should be enough to make you happy...
I know that by doing #'s 1-5 on my truck, it made a world of difference! I'm about to experience number 6 tonight, when I finally get my driving lights all wired up! I also did all of the above on my dads Dodge Dakota, and its like daytime in front of that thing now! With the driving lights burning, you'll actually blind yourself in oncoming road signs!
