I modified these a while ago, but in doing so, I had to scrap the original electronics. I made a quick little circuit with two small 2.2 volt green LEDs for the lenses, and one red LED for the little red cover I installed on top of the goggles. They're powered by a couple LR44 batteries hidden behind the face pad, and are controlled by a small toggle switch on the bottom.

Not super accurate, but I think it makes these look 1000x better.
