LED Configuration for Arcadyan AW1000

Permission to post. I am working on a custom firmware and successfully built one. The only pending is the LED configuration. It only have the light on power.

I would like to work on the rest of the LED like for example on signal, if it has good signal it will turn green or blue but if poor it will turn red or orange.

Any starting point / leads how to and where to will be appreciated.

Note : im still learning openwrt
