i made two blocks, a lamp that is on & a lamp that is off.
The lamp that is on relpaces itself with the lamp that is off only if there is no redstone signal.
The lamp that is off replaces itself with the lamp that is on only if there is a redstone signal.
both of them have the "can provide power" button on.
both of them have the hardness and resistance of a normal redstone lamp.
the lamp that is on drops the lamp that is off.
the lamp that is on is upposed to provides the same light level as a normal redstone lamp but it doesnt for some reason.
everything is like a normal redstone lamp (except the texture) but i keep getting this error message. i tried to go to the file and change it but it always changes it back even if i reload after changing it.
