All lighting went out

I have a '76 Duster with an early 360 and took of from a stop sign a little heavy and everything went black. Still have power to the vitals but no lights whatsoever. Before they went out they almost flashed a bright blue, almost like the voltage just shot up. Checked ground, all fuses and for any burnt or bare wires but found nothing. Any suggestions where to look next would sure be appreciated. Thanks20150628_154634.jpg 76 Duster.jpg
