[H] Android app?

[Winterlight]

I own a Moto G5Plus. I previously owned a G2. The G2 had a 
notification blinking light... just like the old Razer. With the 
light I could just glance at my phone to see if I had messages but 
now with the <advanced G5> I have to manually check it which is a 
huge inconvenient annoyance. It has also caused me not to get my 
messages in a timely manner. So can anybody recommend an app that 
will help me out? Thanks
