Minecraft - Furniture/Detail: A Stop Sign and Traffic Lights

I had an urge to create some public signs in Minecraft. Here's a stop sign. I created it using two nether brick fences, a redstone block, and a sign. On the sign, I made an octagon and wrote "STOP."

I used nether brick fence and signs to create an intersection traffic light.

Zoomed in.

Finally, I made one of those smaller traffic lights. Nether brick fence, coal blocks, item frames, and dyed wool.

You can also replace the coal blocks with redstone lamps for a different look. This lead me to an idea about giving this streetlight function by adding levers at the back to show one of the lights "glowing." However, ...

...the lever will also affect adjacent blocks, rendering it unusable.

Well, that's all for today. Have a good night!
