voltage regulator is getting bad have your alt tested
If the headlights are halogen, these tend to be sensitive to voltage spikes. Before replacing the headlights, have the electrical system checked for faulty voltage regulation.
There is a voltage regulator located on the internals of you alternator replace the altenator. Voltage regulator keeps voltage constant and stops spikes in power output, this is what is causing your headlights to blow.
The voltage regulator is built into the alternator.
12 volts.
No, it is inside the alternator.

The alternator may not be charging. There may be a bad connection from the battery positive or negative to the vehicle circuits. The headlights large current draw is causing the voltage to drop below what the computer needs to operate properly
have you try the fuse box? check for voltage on the wires going to the socket if not simply trace back your wires until you find the open source. it could also be the headlights switch.
Being old is usually what does it. If new headlights burn out, do a voltmeter check. If the voltage is much over 14, your voltage regulator is fried.
