That doesn't make any sense - you're not group riding in the dark vs being seen while it's daylight at the same time.
If it's night time, I have no problem seeing people with blinking superflash tail lights while driving my car. I can see them a quarter mile ahead of me (and if I can't see them because of obstructions, the light intensity doesn't matter for the most part).
If it's daytime, then the light doesn't bother other people in the group ride - because it's daytime.
