Minecraft tool for light levels?

I'm just building a big house and wanted to ask how you can turn it on so that you can see the blocks where mobs can spawn, as you see it with some Youtubers (e.g. Sparkofphoenix). Is there a tool for it or is it a key combination?

In the earlier versions 1.7.10-1.10. If that was possible with the f7 key, I don't know whether this is also possible in other versions

Ok, thank you in advance I'll try it out

Unfortunately no longer works, but thanks anyway

This is a light level mod. The mod is called https://www.curseforge.com/...ht-overlay.

But that only works if you have a light level mod.

Fi

Ok, can you use the vanilla version? Because it's called overlay

Po

No, you need a modloader (Forge, Fabric or Rift) for this.

Ok, I can't do anything with it because we have 1.16.2 Vanilla on the server, but thanks for your help

This is a client-side mod.
