Fallout New Vegas

I'm about to get pedantic.

Those scars were not the result of faulty wiring. Early belter space suits were built cheaply, often without proper insulation, especially around the mating area of the helmet. The suits would heat up in the sunlight, but without an atmosphere (and thus convection), wouldn't be able to cool down, and would burn the unprotected skin. Heat management is also why contemporary EVA suits are white.
