Review on GASHER 12V/24V/110V 20MA Energy Saving Indicator Light Mounting Hole Size 22Mm (7/8 Inch) White 10 Pcs by Robert Lemons

You need to drill a hole for the lantern first. The light needs to be installed in the hole before you can connect the cable. If you install it into an existing panel. Inserting the wire and tightening the screw at the same time is very difficult. The connection should be on the back, not on the side. I am very disappointed and will not order again!
