You might think darkvision obsoletes the Light cantrip, until you have a ranged combat under conditions of partial lighting, and then you realize that lighting control (including Dancing Lights) has the potentially to be simply incredible. Darkvision is extremely short-ranged, but if someone lights an enemy up with a torch you can fill him full of arrows from 600' away (or more if you use a ballista, and at advantage if you're a Sharpshooter), and he can't even reply effectively. Nor does he get a saving throw against being lit up. Lighting and cover are the two most powerful environmental advantages in 5E, followed by caltrop deployments and high cliffs to push people off of.
Note to self: when PCs land on the moon next week, try to make sure a fight happens in sheer mountainous terrain under a gigantic lunar shadow.
I would agree that beginning parties tend to greatly over-value their darkvision. Remember, darkvision only gives the effect of dim light in total darkness. This gives disadvantage to checks relying on sight, and means an effective -5 to passive perception for things like spotting traps. The range of 60' also comes up all the time — that's easily within range for a short bow, let alone a long-bow. Darkvision is great for sneaking up on somebody in the dark, but it doesn't make actual light obsolete.
On the other hand, lots of classes can have light as a cantrip, and you probably don't need more than one character to take it. So, in a party with several casters, that still leaves several other cantrip slots.
But yeah, light is great and allows for all sorts of creative uses. Much better than a torch for everything except starting fires.
