Minecraft - Redstone lamps in 1 block wide stairs?

I have a little problem with Minecraft.

I have a freestanding staircase that is exactly 1 block wide.

Under the stairs, the area is filled with blocks.

So that the padded does not look so stupid, I wanted to put there lamps. Redstonelampen look somehow best.

My Problem: How to light up the upper redstone lamps, without which the stair becomes wider and without which one sees Redstone (torches).

The bottom row is simple. I just put a torch under the lamp and the lamp over it. The lamp is then seen from both sides of the stairs and not a redstone.

Now comes over the lamp a normal block and then another Redstonelampe. How do I get the upper red tone lamp on, so you do not see anything?

I would somehow have to pump the one block next to the lamp, but I do not know how I do it at 1 block width, without what you see.

I suspect that is not possible or? Will you be happy with Glowstone?

Here's an "image": T is the stairs. B is a block. L is a redstone lamp. I would like to illuminate L1 and L2 somehow. There's a redstone block hidden in the bottom of the floor under the stairs for the lower lights to shine.

How about a real picture? The under which I can imagine zero. Since I have a better picture only of the text in the head.

Look at the discord server and ask in the channel, redstone. "https://discord.gg/5cGcnDr

I was helped there before. Ggf nutz @ HelyusHD
and ask him. He was the one who helped me. Took me briefly on a server where he was looking for a solution with me.

EDIT: Alternatively, look if it can use ne ID for the active lamp.

Send picture or adde me on discord I do not know day degree ask me later if you want

then I will help you

Thanks, has meanwhile done. Sea lanterns look much better and do not need a Redstone signal.
