This is the second time I have seen electric sparks at home. When I switched it on, a very bright, white spark appeared at the switch. Please pray in Jesus' name that the root of the issues will be properly understood, and that the technicians will take all necessary precautions to protect the house from fire or electrical damage. Many thanks!! Update: A tingling, prickling sensation can be felt on the surface of the light switch (or plug) again. There was an electric spark again. Please...
