I recently got some of these auto-dimming, light-sensitive, night light / emergency flash lights and plugged one in into a grounded (three-prong) GFI outlet in the bathroom. In the few days since I did that, I've found twice that the GFI had tripped. I have not had trouble with this outlet before, including when using it with a simpler kind of light-sensitive night light.
- Neither the current night light nor the older one have a ground prong.
- The outlet is dry and clear of obstructions.
Why would this kind of night light cause the GFI to trip? Should I simply not use this light in this outlet, or does this point to a possible fault in the circuit? How would I check?
