Activate redstone lamp with command block?

Question

I've reviewed several articles and other questions (here's one), trying to trace down a way to activate a redstone lamp using a command block. Everything I've found says to use:

/setblock x y z minecraft:redstone_lamp[lit=true]

I get a syntax error within the braces saying that lit was unexpected:

How can I activate a redstone lamp with a command block?

Answer 1

In Bedrock edition there's a seaparate object ID for the lit block state of the redstone lamp:

So instead of using block states like you would in Java edition:

setblock x y z redstone_lamp[lit=true]

You should specify the object ID for the lit redstone lamp:

setblock x y z lit_redstone_lamp

Answer 2

If you are playing Java edition, I don't know how I can help you,* however if you are playing bedrock edition, you can use the command: /setblock (x y z) lit_redstone_lamp and you are good to go. Or you can use the testfor command to detect what you want. So if it detects what you put in the command, it will give a direct output from the command block through a comparator.

*I don't play Java edition, only bedrock. Not that I don't like it, but because I can't get it, unfortunately.
