Is there a way to speed up my led light notification on my lg flex 2 phone without needing a new app

[AC Question]

It takes 10 seconds not that bad but I want to know if there is a way I can speed that up to 4. I tried in the settings and found nothing please help.

Unfortunately you can't. Something like this needs a third party application to adjust the frequency of the LED.
