Things I've done with Dancing Lights in table top include:
Faking the appearance of an incorpeal undead creature.
Lure a patrol of enemies off a cliff to pursue the "torchlights" they had caught sight of in the middle of the night.
Spread throughout a room to create several points of bright bright light.
Send signals.
Startle an enemy by putting one in their face to interfere with their next attack.
provide a path for an ally to follow.
support a bardic performance
A few other things here and there.
But yeah, I expected it wouldn't have as much functionality as it did in the tabletop, I'll have to consider the fact Darkvision just reduces things to Dim rather than normal vision.
