Yep, they're the dioder lights. It's like they were made to go in the detolf and light 1/6 figures. Wonder if it's a Swedish thing. Must love their figs a whole lot too.
I've gotten a couple messages about how to set up the lights and hide the cords. Though it's not related directly to BL, I'll post it here.
Ingredients: 1 dioder led light strip; 1 ikea detolf shelf
1. Cut off about an inch of the plastic strip that is used to hold the two glass panes of the detolf together. When you assemble the shelf, this gap should line up at the bottom of the shelf. This is the gap the wires of the dioder strip will exit through (you could exit out the pre-drilled hole at the top, but some of the bottom light wires won't be long enough. Likewise, you could exit out the front glass door, but they'd stand out a bit). IMPORTANT - you will have to place the wires through the gap in this strip while assembling the shelf (specifically before you place the wooden base on). the ends of the lines won't fit through when it's closed up, so it has to be done before...
2. Once the shelf is assembled, it's time to start running the wires down. Starting with the top one, I cover it with some dark tape (electric). Attaching the light in the center of the top wood panel, and running the cord to the back of the base...
3. I then tape the cord up on the backside of the metal rod that runs down the back of the shelf. The cord from the next shelf is then run along the bottom of the metal rod the glass pane sits on, to join the cord from the shelf above on it's way down...
4. I repeat this task with each shelf after, running and taping the cords to the backs and bottoms of the metal rods all the way down, where they sneak out the bottom back of the shelf, nearly unseen, through the gap created earlier.
It's all pretty simple and straightforward. But very tedious and time consuming, at least for someone as fidgety as me. Nonetheless, when the task is complete, voila...
Cheers!
