Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
Which bulbs have failed?
Are the others still dimming?
What is the battery voltage max/mon while running at various rpms and with various electrical loads on?
Sorry I logged after waiting 30 minutes.
Since you do not have the vehicle are you asking for information just to know what to expect hen she takes it to a shop?
Step one they need to monitor the alternator to confirm it is not overcharging. It should be 13-15 volts.
Net they need to confirm the battery is good and the connections are clean.
Then they need to monitor the power and ground to the headlights to make sure there are no resistance issues with the ground and no power surge on the power wire.
