The OP obviously has a bad alternator. Probably one or more of the
diodes have shorted.

Shorted - or open - diodes reduce the output capacity (and the apparent
average voltage) of an alternator. This would make the bulbs last longer.
High output voltage is caused by regulator failure. Depending on the
vehicle, this may be an integral regulator, and external regulator, or field
voltage supplied from the vehicle's PCM under software control.
That said, the voltage would need to be really high - much higher than
14.something volts - to kill bulbs in two hours. So high that the battery
would likely be literally boiling due to overcharge.
Remember, the OP threw us some info - probably to see what would happen -
and hasn't been back. He's posted exactly twice, and pulled a similar stunt
on
alt.autos.dodge.trucks .......
"Fuel gauge is erratic,when the gauge is on E,I'll fill up and only take
7,maybe 8 gallons of fuel.thanks"
He also set a "No Archive" on the original message in both cases.
