I think every house need a Voltage Detector. Especially when house owner changes the light bulb.
The day I send my car to Goodyear for service, is a good day. I have a walk and found a store. I went in and purchased this Greenlee GT-16 Adjustable Non-Contact Voltage Detector. It is just below $30.00.

It is a little bit expensive, but it worth.
Let us see the features of it.
