Fullbright by Finnvian

Fullbright lets you see in the dark by modifying the brightness of Minecraft. This is a useful tool which works in all Minecraft vanilla environments such as the Overworld, Nether and the End. Additionally, this Minecraft resource pack is compatible with other resource packs, so you can use the pack that you want while having Fullbright.

Information:

• You can set your in-game brightness to 100% (Bright) to enhance the brightness effect.
• If you use another resource pack and it modifies "shaders", set the Fullbright resource pack to the top of the list to ensure it works.
