Effect creator individual brightness for white lights

I have a bunch of white hue lights (the ones with only brighntess control) and wanted to get a running light type effect.

When I use the color frame I can set the brightness of all the lights but not single ones but when I use a pallette frame where I could set individual brightness for each light the effect simply doesn’t run. I guess because the lights don’t know what to do with the color information. This makes the effect creator pretty much useless for people with only white lights.

I guess an easy fix would be a pallet, that works with white light’s. Or brightness sliders for each light in the color frame.

Would be great if this could be fixed.
All the best!
