Question regarding notifications & the notification light...

I want txt message notifications in the status bar, and the notification light to blink. For Gmail I want the status bar notification but I do not want the notification light to blink.

I used to set a custom value for the Gmail notification light to black, which would essentially turn off the notification light when I received an email. However, I realized that if I got a txt message followed by an email, the notification light would go black so I wouldn't know that I received a txt message without turning on the screen and looking at the status bar. I'd prefer the notification light not be affected by the email and it would remain flashing since I received a txt message.

Is this doable without a notification light control app? If not, any recommendations for which app to use?
