It is used as an indicator light for the operation status (operation, preparation, stop) of the injection molding machine.

We use it for more than 100 molding machines. Although it was only red indicator light in the past, after switching to this product, the operation status is displayed in three colors of driving (green), preparing (yellow), stopping (red), making the situation easier to see. The price is cheap, it is useful.
There is no problem with quality because it is a manufacturer item. The price is higher than via a trading company but it is saved because the delivery date is short. I am happy if the price is low with this, but it can not be helped.
