Home Automation with ESP8266, Amazon Alexa,Google Home and Sinric Pro

I have code that turns on/off LED lights. I'm having an issue where when I turn on/off the "Blue Glare" the Red Bulb turns on/off and when I turn on/off the "Red Bulb" the Blue Glare turns on. I am using Sinric Pro and I have all the correct Device IDs next to each light but the problem still happens. Can anyone help me?

Control/signal wires for RelayPin3 and RelayPin5 are on the wrong pins (12 and 13).

RelayPin3 should be 13?
RelayPin5 should be 12?

You have them on the wrong pins.

What should be the correct pins

Read your documentation and your code. (and my answer, twice)
