This is a great item if you want a professional look to the installation of an LED in a panel on your layout.
Once a hole is drilled, in the panel, the bezel can be inserted into the hole it'll make the edges of the hole look "clean". The LED is then inserted from the back side of the bezel and is held in place by an edge in bezel.
