In my Xperia M5 blinking rate, i mean LED notification blinking interval is too long and it is very tough to look at the phone for more than 6 seconds to see a notification. Is there any way to change the frequenct to 1 second or 2 second. I used third party apps but no use...
You cannot by default but perhaps a 3rd party app from play store can help.
Hey @Sanjayjmc,
I'm afraid that there is currently no way to adjust the interval rate by default as mentioned by @alexdon, but there may be third party apps which allow you to customize that. I have not tried it, but I have heard that Lightflow is a popular LED app in the Play Store, maybe it would be worth giving it a shot if you have the time to do so?
Please let us know if you found a way to adjust the setting so that other users can benefit as well! 
I tried LightFlow and it is similar like other third party apps. It doesn't control the LED blink interval. There are many lower end and cheaper mobiles in the market which are doing best in the LED notification feauture and my Previous mobile Xperia M dual was awesome but i dont know that happened to my Xperia M5 Led Module..
Ah, that is unfortunate.
There may be more third party alternatives, but in any case I will make sure to forward your suggestion internally as user feedback!
