The Force Field around the neon Glass

Electric Sign Repair Tutorials
The glass on a neon sign has an electric field running on the outside of the glass as it does on the inside . The outside electric field is not very powerful but it can give you a small shock. That is why the glass has to be at least an inch and a half away from any metal part , because that electricity will create a small spark that will heat up and eventually pock a hole on the glass and the gas will escape making the neon section useless.
