Blue ESP8266-12e tx light staying on - esp8266

Question

I have some code I have been putting on an ESP8266-12e board. Until recently it always worked fine. Now though when I finish uploading the code the blue light on the ESP8266-12e is staying on. I have tried it on two different board and the blue light stay on on both. I can't figure out what I changed in the code.
I have decided to put it up and have everyone look at it and let me know what I may be missing.
I hope someone can find something.
My code:

I hope it is not toooo long.
Anyway I hope someone can find my problem. Everything works ok with the blue light on it is just know supposed to be that I can tell.
When I upload another code it doesn't stay on so it has to be in the code.
I will keep looking.
THANKS

Answer 1

So I got the blue light to go off. Instead of pinMode(D4,INPUT); and digitalWrite(D4,LOW); D4 is pin 16 which is the wake pin. So I had to define it thus #define LED3 16 and then pinMode(LED3,INPUT); and digitalWrite(LED3,LOW); I will change my original code to reflect these changes.
