Review on 📈 Gasher Energy Saving Industrial Electrical and Controls & Indicators: Mounting Indicator for Efficient Energy Management by Tres Carmon

I have them to indicate power (green) and closed remote switch contacts (red) for my dust collector. Since I'm using a wireless remote switch to turn the fan motor on and off, I need a contact closure indicator. Indicator lights are easy to connect and their ability to operate on 12V, 24V and 120V AC makes them versatile for use in many projects. I am ordering more now 6 months later for another project requiring indicator lights in my workshop.
