Hi @G_W1Z,

Thank you for reporting this behavior. As far as I can tell you are expecting the following to happen, correct?

 ![image](https://web-assets.waze.com/discuss/prod/original/3X/b/9/b9bba11965290f4464477df24c6301e241a4ab10.jpeg)  
Currently, it will create TLs for all segments that end in that node only when adding a new TL, but this does not work the same way when snapping an existing TL to a node.  
Please let me know if I got it right.

All the best,  
Olesya

You are correct. Maybe I assumed the same behavior with existing TLs.

Thank you for confirming @G_W1Z. Since this behavior only applies when adding a new traffic light rather than snapping an existing one, I’ll mark this as WAD.

If you have any questions, please let me know.

All the best,  
Olesya
