The easy solution would be to just add a switch to kill the grille portion.

The option to turn only one on at a time or both would be nice.

You are good with the grille and halos being on at the same time?

Different whites will be upgradable.

RGB halo kit. I would like to add grill lighting in addition to the halos, would I need to wait for the new hardware to come out or will the current setup be able to upgrade to support more leds to sync with the halos? Also, will the different colors of white be upgradeable with the current setup or need to wait for new hardware to come out?
