With LLI (Light Level Indicator) you can see where mobs can and cannot spawn. It works in all dimensions and in the ocean as well. Great way to mob proof villages so no zombies kill your villagers. Very effective for lighting up surrounding land around mob farms to maximize output.

Light Level:
7 - 0 red to black (Most hostile mobs can spawn at light level 7 or less)
10 - 8 yellow to orange (Blazes can spawn all the way up too light level 11 in the nether)
14 - 11 white - blue - green

Note: THIS DOES NOT WORK WITH NIGHT VISION! If you have night vision applied it will not display at all. Be careful using around an active conduit or the texture packs effect will disappear until night vision is gone.

Note: When first loading texture pack its a good idea to be standing by a torch or else once loaded it will be pitch black on your screen ; )

Note:
- This requires OptiFine to work.
- This ignores sunlight level.
- Works with all resolutions.
