I had the hardest time getting the WhatsApp notifications to work using Light Flow on my Note 3, but I finally figured it out. Here is the solution.
Normally you need to turn on Light Flow in the Accessibility settings on the phone. But not for Android 4.3 and above. There is a note when you turn Light Flow Accessibility on and off saying such. So leave Accessibility off for Light Flow. Instead go to Phone Settings/Security/Notification access and check the box after Light Flow. And now it should work.
Hope that helps you.
