No, dimming can't blow the head lights. But too high of a voltage can.
What does the electrical system max out at (ie. when the radio is not
playing)?

The max I've seen when first starting the car on a freezing 20 degree
F day is 14.6V. On a typical 60 degree F day I'll see 13.8V at about
2000 RPM. Voltage regulation looks normal when I am not pushing my
system. The driver side headlight is the original OEM unit and it is
10 yrs old. I've gone through about 5 bulbs on the passenger side, 2
in the past 2 weeks. I've been using Sylvania replacement bulbs from
PepBoys. Maybe I should try an OEM bulb on the passenger side this
time.
