Light-UPLocks, retail ${?}
Manufactured by (Unknown) for Wall*Mart (

This is an unusual gadget to say the least. It looks and works like your everyday combination padlock, but when you push a small button on the knob, you are rewarded with a miniature light show from the RGB (red, green, blue) LED and driver circuit cleverly concealed within!!!

* Unit was found at a Wall*Mart on the east coast of the US in late-2006; I was not able to find it on their website, so the URL above simply leads to their front door.


Use this padlock as you would use any ordinary combination padlock...turn the knob three turns to the right and then dial in the first digit...turn the knob one full turn to the left past the number you arrived to in the "right" sequence and then dial in the second digit...turn it to the right again until you arrive at the last digit, and you should then be able to pull the hasp (the curved metal thing) open.

To turn on the light show, press and release the small grey button on the knob. The LED inside will then come on, and perform a colorful light show for 27 seconds, then automatically switch off.

To change the batteries when necessary, hold the number dial with one hand, and rotate the clear plastic knob clockwise (as though tightening it) approximately 1/8th of a turn, and pull the clear knob free of the lock body.

Turn the clear plastic part so the knob faces down, turn the battery door counterclockwise (as though loosening it) approximately 1/6th of a turn, lift it off, and set it aside.

Remove the two use CR1616 coin cells, and dispose of or recycle them as you see fit.

Slide two new CR1616 lithium coin cells in the battery compartment one on top of the other, orienting them so their flat-ends (+) positives face up. Be sure they both go under that metal contact strap.

Place the battery door back over the opening, and turn it clockwise until it drops in; turn it clockwise some more until it stops turning (this should be ~1/6th of a turn from when it drops down).

Place the knob assembly back on the dial of the lock, hold the number dial with one hand, and turn the knob assembly clockwise until it's seated firmly in place.

Unable to measure current usage due to how the product was constructed and how it operates.

I found that the knob assembly on the test sample to be a rather minor pain in the toilet muscle to remove & replace.

This padlock was meant to be used as a padlock in a dry area, not as a flashlight meant to be carried around, thrashed, and abused, so I won't try to drown it in the toilet 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 (for #1) on it, run over it with a 450lb Celebrity motorised wheelchair, or perform other indecencies on it that a regular 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 combination for the lock is printed on a disk of paper affixed to the back surface of the padlock; please peel this disk off before using the padlock to actually lock something, or you'll very probably be sorry.

I just tried using the lock in the dark, and if you hold your thumb or finger on the top of the knob (thus covering it) while dialing the combination, it is bright enough to read the number dial of the lock at night.

It is approximately 7.1 megabytes (7,327,000 bytes); dial-up users please be aware.
It will take no less than forty five minutes to load at 48.0Kbps.
I cannot provide it in other formats, so please do not ask.

That music playing in the background is from the demo "Mag Factor Three" for the Commodore 64 computer from late-1992.
When that demo was made, I ran a C=64 demo group called TDM
(The Douched Moose); and I wrote numerous demos for that computer.

This product is not sound-sensitive; the sound may be ignored or even muted if it pisses you off.
