you will have to cut the bottom of the chucks and hollow it and then put your own lights in them, they dont light up by them selfs sadly.

Mine do. Keep them in bright light for a minute or two first, then carry them to a dark room or another dark setting. The interesting thing about these "alien eyeballs," as I call them, is that they hold their glowability noticeably longer when they are exposed to natural light rather than artificial! Go figure!

They glow green. Protip: The packet comes with white putty. It's not enough for all of them, but when the stars glow, it will show the putty in the background.

They came with a wax block that u attach to the bottom and light. Just make sure you attach securely before lighting, as they fall off easily.

The letters on the keys do light up as well. There is a light button to turn the light on/off and adjust the brightness.

They are LIGHTS--they come on when it is dark out. They glow dimly, and if you move near them, the motion detector brightens the light.

Mine does not light up like the picture. There is one color at a time, with each color lasting four or five seconds before changing to another color. It's still really cool, though.

Yes it lights up . Doesn't make any sounds and You need to buy your own batteries. I believe they are AA

You could use small flat head screws to fasten the holders, then the lights just pop into place. I did that with wooden cabinets. You Might have to pre-drill the holes. surprisingly they give off a lot of light.

Yes. They work just like normal blacklights. Depending on the color of your pipes/fluid yes, the lights could make them glow.

They open on each side. They are like a push in with a magnet type if that makes any sense :-)

No, they don't light up, and so the answer is, you don't know what you're pressing when it's dark. So I don't recommend using it in the dark. :-)

I'd love to answer your question but I've had mine for a week and they've yet to light up at all.

Mine look like they glow after they have been also. They eventually go out. I haven't had any trouble so I'm sure it's OK.

They come with clamps that clamp to the light. If the shelves are wood you can use screws to hold the clamps to the shelves that will hold the light up.

You have to "charge" the area with light and then it will glow, it's not radioactive lol
