Will be working on adding Andon light stack functions to a POC app today, and when I checked [this KB article](https://support.tulip.co/docs/assembling-the-light-stack) it included the following instructions and link: Confirm that the Andon Light Stack is working by: 1. Selecting [Andon Light Stack Unit Test](https://tulip.co/library/apps/light-kit-unit-test/) on the Factory Kit Navigator Page 2. Follow the instructions on the Andon Light Stack Unit Test Application and see whether the red and green lights come on. Unfortunately the link goes to the Light Kit Unit Test, not the Andon Light Stack Unit Test. ---

Hi Jim! It seems the Andon Light Stack Unit Test was deprecated from the library, and I’m actively figuring out if the Light Kit Unit Test was meant to be a replacement. Either way, I will make sure this article gets updated with appropriate info and references. Thanks for letting us know! ---

**Follow Up:** Tulip discontinued the Andon Light Stack Kit in June of 2022, and shortly after the Andon Light Stack Unit Test was deprecated from the library. I’ve put callouts in this article to make users aware of this and also direct them to other content that might be helpful instead. Hope this clears things up!
