I really hate the low light visions and abundance of light cantrips in this game. My last campaign had a Bard, Sorcerer, and a Cleric which meant there were 3 light cantrips going at all times. One solution to that problem I am using with my next campaign is to make light cantrips into a concentration spell.
The Sorcerer might have to decide mid dungeon to drop his light cantrip on the fly if he needs to cast Spider Climb or Hold Person. That Bard isn't going to be able to maintain his light if he wants to cast Tasha's Hideous Laughter or Faerie Fire. The Cleric has to drop his light if he wants to cast Silence or Spirit Guardians. These are just a couple quick examples but it forces them to make a choice. Dropping that light cantrip might throw a part of a room into darkness, creating a danger for the players.
