I would go with the clear lens OEM-style reflector light. Given your truck is at least a few years old by now (you said it was a Columbia), and with most of the parts for it made in either Mexico or China anyway, a new set of lenses sometimes is the best option if the lenses are fogged over. I suggest getting the lenses at a Freightliner dealer, since they often have great deals on the parts, and the service is superior to most of the chrome shops and suppliers who have the same part.
There is also a repair kit for lens hazing, but it requires a cordless drill, lots of elbow grease, and is almost as expensive as replacing the lens itself. It's made by 3M and is called the 3M Headlamp Restoration Kit. In my experience, the kit requires more work than it's worth.
For the bulbs, I would spec one like the Philips CrystalVision Ultra or the Sylvania SilverStar Ultra. Replace all the bulbs at the time you replace the lenses, and thoroughly inspect the wiring to make sure everything works and is up to code.
One more thing: Make sure, once your lenses are in and your bulbs are working, that you properly aim your headlights. You can refer to the Freightliner Driver's Manual and Service Manual for more information on how to perform this procedure.
