I just replaced alternator which I have done many times now but this time when I was driving at night the lights have a noticeable pulse. I have xenon lights in it as well.??
SOURCE: Battery dosn't charge, alternator/voltage adapter test's good.
Did you test the Alternator on or off the truck? It might be a problem with the control system to the Alternator. The regulator need a battery feed to work, It is usually ran through an alternator fuse.

If the battery and alternator tested fine. I would have the charging system rechecked when engine is hot and at high rpm's. This way the checks are being done as if you were driving and driving for a long time. Alternators can work fine when cold but weaken when hot or stop working. This problem is not rare but only is seen occassionly. Unless it was checked at an electrical shop the average shop doesn't run these tests for they don't see the problem often enough to automaticly run them at all times. Good luck and let me know how you make out.

if brighmess increases with speed then alternator must be okay,try the belt for tightness/slipping.
