When a torch is placed a "TorchTimer" Bat is summoned at Y=0 (in bedrock) that
way the entity is completely out of the way of all players. It also does need
invisibility potion effects.

When the 'timeout' is reaches all torches in that column is removed.

  Start Function
    /scoreboard objectives add placeTorch stat.useItem.minecraft.torch
    /scoreboard objectives add TorchTimeout dummy

  Clock (Fast)
    # Set torch timeout entity  (bottom to top)
    /execute @p[score_placeTorch_min=1] ~ 0 ~ /summon Bat ~ ~ ~ {CustomName:"TorchTimer",NoAI:1b,Invulnerable:1,PersistenceRequired:1,Silent:1b}

    /scoreboard players set @p[score_placeTorch_min=1] placeTorch 0

  Clock (slow) - minecart-in-web clock
    # Increment timeout count
    /scoreboard players add @e[name=TorchTimer] TorchTimeout 1

    # Timeout - remove torchs, kill entity
    /execute @e[name=TorchTimer,score_TorchTimeout_min=<desired time>] ~ ~ ~ /fill ~-5 0 ~-5 ~5 255 ~5 air 0 replace torch
    /kill @e[name=TorchTimer,score_TorchTimeout_min=<desired time>]

  Testing - See Torch Timer Bat counts
    /scoreboard objectives setdisplay sidebar TorchTimeout

Notes:
 * The value 90  in the above is the time out. Adjust to suit (1-2 hours)
 * For debugging change bat placement to ~2 to place it above the player.
   This does not effect the torch removal effect.  This is not recommended
   normally as the bat (even if also made invisible) gets in the way of
   players wanting to place blocks, with at that location, or through that
   location.

The value 90 in last two commands is the timeout, and with 2 webs is about 1 to 2 hours. adjust to suit.

The result of the mod has been a large number of pumpkin patches, and having
to prepare your lighting before caving (not more simply making torches in caves).
Also having to grow them limits the rate at which players light up areas. And
having limits on the amount of lighting placed in caves, results in more dark
spots and thus more mobs, and the danger in any caving adventure.

I suppose you could add something to make jack-o-lanterns also time out but
last a LOT LOT longer, but that has not been done. I felt it would produce
too many entities.

FUTURE EVIL IDEA... spawn N entities, player spread them to randomise, then in
5x5 columns around entities, remove torches, and replace jacks with pumpkins,
so that lighting fail at random through out the area. This may be the better
option as the entities no longer need to remain active all the time.
