WELCOME to the club!
I'm the 2nd owner (Col. Walt Cunningham USMC, Apollo 7 was original owner) of a Hennessey Stage IV NSX that I added a CompTech super charger to.
Very frustrating and sorry to hear this. Since car "died", I'd check the negative terminal and ground (a known potential weakness).
EDIT-I missed that this is NFGT, I was thinking about 05/06 version...Sorry.
I also understood that the headlights "breath" (have a vent system) and moisture and contaminants in the atmosphere cycle through there and sometimes get deposited on the glass on the inside.
