Blue LED "Belly Button Light", retail TBA
Manufactured by (Unknown)
Last updated 07-02-08

The Belly Button Light is a type of LED "rave light". It features two "chip-type" blue LEDs, plus an IC that flashes the two lamps rapidly in an alternating manner.

It comes in a ribbed metal body; the LEDs and IC are protected by a low epoxy dome; and it uses a pair of CR927 lithium button cells to power itself.

It is equipped with a tiny but very powerful magnet that allows you to affix the tiny light to various ferrous surfaces like bicycles and metal components of automobiles.


To use the Belly Button Light, just give it a gentle but firm clockwise twist. Careful, not TOO hard. Turning it off is just as easy; twist the other way until it goes off.

It comes equipped with a small, thin disk magnet inside the bottom of the light; this allows the light to "stick" to any ferrous (magnetic) surface such as iron, mild steel, nickel, cobalt, or gadolinium.

Because this light use powerful magnets, you should not use or carry one in the same pocket as your bank card or other card with a black or brown magnetic stripe on the back, and you should not bring it within a foot of computer diskettes, computer hard drives, music cassettes, cassette players or walkmans; or video tapes & players. These lights will also cause discoloration of the picture on CRT (boob tube) TV screens and computer monitors if brought to within 2" or so of the screen or placed on top of the set, so you should not store or leave these things on top of the TV between uses. When not being used, sticking them to a larger piece of ferrous metal, such as the refrigerator or a metal doorframe, greatly reduces the emitted magnetic field so your bank card won't become scrambled if you happen to walk by the light with your wallet in your hands. :)

To change the batteries in your Belly Button Light, unscrew the two halves until they come apart.

Remove the two 2xCR927 lithium button cells and the disc magnet (it will almost certainly be sticking to the cells) from the bottom half of the light (the part not containing the LEDs & flasher).
Keep the disc magnet, and dispose of or recycle the two used button cells as you see fit.

First, place the disc magnet in the light's lower half, then place two new CR927 button cells in; orienting them so the flat (+) side is downward. Try to put that first cell in so it's in the center of the chamber, as best as you can get it. Use the tip of a pen to move the cell to the center if necessary. Lay the other cell on top of it, being sure the flat (+) side faces down. With both cells in there, screw the two halves of the light back together, and back off a bit once it springs to life.

If you love shiny, blinky things, you'll love the Belly Button Light.

The Belly Button Light is meant to be used as a blinking novelty item, not as a flashlight meant to be carried around, thrashed, trashed, and abused, so I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a patio, let my housemate's citty kats go to the litterbox on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again (yes, I watched four episodes of this program just this last Saturday!!!) - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

The Belly Button Light produces a wide, 180 degree swath of light. Although it isn't meant to be used as a flashlight, you could use it as a rather dim (short range) one if the need comes up - and the blinking effect does not piss you off, that is.

I have an "outie" so I cannot use this product in my belly button, but somewhere between
"some"and "many" people have "innies" and could use this product in their belly buttons.

I cannot provide it in other formats, so please do not ask.

That sound you might hear is Star Trek: The Next Generation playing on the boob tube.
This product is not sound-sensitive; the sound may be ignored or muted if desired.

Test unit was sent by B.R. for spectroscopy, and was received on the afternoon of 06-30-08.
Although it was only sent for that particular test, I thought it was novel enough to write a web page just for it.
