How do you define successful/unsuccessful? Maybe you can use a Status node to track the status of your HTTP node.

What are these red and green lights?  
How are they connected to your Node-Red PC?  
Do you have transistors/relays to control them?

I created a virtual led on node-red and I'm testing on that led. I don't have a physical led for now.

No, I'm done with the button side, now all I have to do is turn on the red warning led if the http request is successful if it is successful.

Do you know how to turn the LED red or green with an inject node?

No, unfortunately I don't know, I would appreciate if you could make a sample node structure.

I assume you want to change the color of a `ui-led`.  
So what have you tried?

You should read this about the node:
