The safety issue is one of electrocution of the user, and the only
viable solution is proper insulation. It would be nice if the
insulation allowed the light through as well.
Fusible resistors don't seem to carry approvals. I don't know why,
perhaps they are not considered "safety" related but are typically
used to prevent further destruction. Maybe JW knows?
