Headlights problems of the 2001 Dodge Ram 2500

The headlights on my truck repeatedly go out. Initially this only happened when I switched from high to low beam. Waiting a couple seconds then switching back to high and then to low will allow me to use low beam. However, recently they have failed to come one at all and gone out without any changing from high to low. This was also an issue with my 1995 2500 ram, which Dodge excluded from its recall (99v024).

The headlights are great on low beam but diffuse to the sides on high beams. Very little light is focused on the center of the road. I have had the headlights aligned twice. They are much improved, but still unsatisfactory. New, higher powered halogen bulbs helped some, but the high beam simply "plays out". The lense system seems to not focus light where the driver can see with confidence at highway speeds.
