How can I determine where mobs will spawn?

Question

I've been putting torches all over the place, but I'm not sure if I have enough light to prevent monsters from spawning.

How can I figure out if something will spawn in a certain location?

@ratchetfreak That was old policy. Mod requests are considered topical now, and "what is the name of this thing" that is well documented is also on-topic. The correct criteria for closing a question like this is now "is it too vague to be able to uniquely name what they're thinking of? do we have to play guessing games?" and to close as Not a Real Question if so.
@SevenSidedDie well I didn't know the current policy (either way) on those I just stated that they are similar...
@Seven Should we edit this title? It's entirely too generic.

The best mod that does this is called Monster Spawn Highlighter made by Lunatrius.

You can find it here

Usage is simple. Hit L, click on mobs to select those you want highlighted and select the type of highlight (bottom left). Finally click Done.

Perhaps you are looking for Safe a.k.a "Critter Spawn Highlighter".

	Safe appears to only be available as part of Zombe's Modpack. Do you know if a stand-alone version of the mod exists? – SevenSidedDie Jan 12 at 17:38
	I do not know of any stand-alone mods right now but each mod in the mod-pack can be individually enabled or disabled which could achieve the intended effect. – Steinin Jan 13 at 6:47

SpawnChecker is a good alternative mod made by Japanese modder.

Use Ctrl+Up/Down to switch between:

Up/Down to switch between display options

[Num+]/[Num-] to change horizontal range
Shift+[Num+]/[Num-] to change vertical range
Ctrl+[Num+]/[Num-] to change marker brightness

This is a feature of Not Enough Items (NEI) as of version 1.4.7.0. A red grid showing blocks mobs can spawn on can be toggled on and off with F7.
