Blue LED Light/Pen, retail $ (Unknown)

Last updated 07-06-07

This LED flashlight/ ballpoint pen is a ballpoint pen in a metal body, that features a blue LED in the top of the pen that can be used as a flashlight.

The ballpoint pen writes with black ink, and works whether the LED is on or not.


Batteries are already installed in the pen when you open the package, so don't let the additional ones in the package throw you off - they're spares.

Press and hold down the button on the side of the barrel to turn the product's LED on, and release it to turn the LED off.

To use the pen portion of this gadget, grasp the unit so one hand is on the pocket clip on the barrel, grab the unit near the pen tip with the other, turn the business end of the barrel clockwise (as if tightening it), and the pen tip should extend so you can write with it. Turn the business end of the barrel counterclockwise (as if loosening it) to retract the pen tip.

To change the batteries, hold the pen so the point (the ink portion) is facing downward, and pull the pen apart. Throw the lower portion in the dustbin (garbage can) - O WAIT YOU'LL NEED THAT!!! So just set it aside instead.

Tip the open end of the pen upside down over your hand so that the four cells wrapped in a thin blue plastic sleeve come out. Dispose of or recycle the batteries as you see fit.

Hold the barrel of the pen horizontally in one hand, and slip the new batteries with sleeve in with the other hand. Insert the battery sleeve button-end (-) first. Once the battery pack is in, you can turn the pen base-up if you wish, and push the two pieces back together.
Aren't you glad you didn't throw out that lower portion now?

The pen portion writes in black ink, and appears to write in a quality you might expect from any medium quality to good quality disposable pen.

The LED did not work after I did the battery change procedure; and failed to light when I installed the spare batteries too.
Maybe this pen is just a "tabby-thrashed segment of a sewer pickle maternal parent humper" (toylet words replaced with innocous ones - the correct acronym is PWPOSMF)

I metered both sets of batteries to be sure that wasn't "it"...and...hmmm, maybe that is "it".
One set measured 0.67 volts, and the other set 3.01 volts.
3.01 volts should still allow the blue LED to light at least somewhat though, so the product has indeed failed.

I was not able to measure intensity before the product failed.

Test unit was obtained from an unknown source at least several years ago; I found it while looking for my Wag-A-Flag on the morning of 07-04-07.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.

Product failed before tests & measurements could be completed, so I will issue that dreadful "0 Stars - Whip Out Your Ding-Dong or Sit on the Toilet and Cover it with Uranation" rating at once.

UPDATE: 07-06-07
Both sets of batteries are now deader than would appear (this is a possibility only!!!) that the negative (-) spring is slightly cockeyed; bent over just enough to cause a short circuit when the battery pack is installed and the lower half of the pen pushed on. This action presses down on the battery pack, further deflecting the spring, causing the short.


Batteries are encased in a special sleeve; it is not known whether or not this sleeve is necessary
