Tired of hostlile mobs taking over you base, because you forgot to light up the area? If yes, this is where the Light Overlay mod will help you. Light Overlay is an amazing utility mod that will help you find dark areas within your Minecraft world. All you have to do is to install this mod and hit the F7 key to turn on an overlay which will show you blocks that are dark enough for mobs to spawn. By default, this mod marks blocks using an grid overlay that marks dark blocks in a different colour. But you can use the config to switch this to numbers and each block will have an overlay that shows the light level of the block. You can also use the config to customize colours, overlay radius and other stuff.

This mod offers versions for both Forge and Fabric. The download links below will take you to the official curseforge files page, from where you can download your required version of the mod.
