Light Level Simple is a client mod that shows light level numbers on blocks where mobs can spawn, so you can spot unsafe areas and light them up!

What It Shows
- Block light value on each spawnable block
- Optional daylight row above the blocks light level
- Colors based on whether the block is safe or unsafe
- Dimension specific light levels
Colors
- Custom colors for safe, unsafe and daylight values
- Optional separate color for the daylight value
Visual Customization
- Adjustable chunk range for how far around you numbers are shown
- Independent scale for block light and daylight numbers
- Brightness control from world lighting to fully bright markers
- Separate spawn light thresholds for the Overworld, Nether, and The End
- Toggle safe spots on or off (hide numbers on blocks that are safe)
- Toggle daylight display and whether daylight uses its own color
