Laser LED Light Pen (2), retail $TBA
Manufactured by (Unknown)
Last updated 03-08-09

This is a 3-way device that has the following functions:
  1. Blue LED flashlight
  2. Red laser pointer
  3. Ballpoint pen
It comes in an all-metal body, operates from three AG13 button cells, and has a ballpoint pen that operates regardless of the batteries' State of Euphoria - er - uh - state of discharge (there I go thinking about the heavy metal band Anthrax again!!!).


To use the pen, grasp the unit at each end, and give a gentle clockwise twist.
When finished, perform the same action as above, but twist conterclockwise instead.

To use the LED, press the lower button on the barrel and hold it in to turn it on; release the button to turn it off.

To use the laser, press the upper button on the barrel and hold it in to turn it on; release the button to turn it off.

This instrument comes with a pocket clip, allowing you to carry it clipped into a shirt or pants pocket, reducing the chance that you'll lose it when carried that way.

To change the batteries in your Laser LED Light Pen, grasp the unit at each end, unscrew the two halves until they come apart, gently place the "writing" end on the floor, use your foot to push it to the doorway leading to the basement stairs, and kick it down those stairs so that the hungry, hungry piss ants will think it's something yummy for their insect tummies, find it unpalatable, and take it to the queen -- who just sniffs at it, goes potty on it, and instructs the worker ants to do the same...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Dump the dead batteries out of the upper portion of the product. Dispose of or recycle them as you see fit.

Drop three new AG13 button cells into the barrel, button-end (-) negative first, and then screw the "business-end" back on.

Alternately, stack the cells on a table flat-end (+) positive down, lower the barrel of the light over them, then pinch it off with your finger while picking the light up so the batteries don't fall out. Then screw the "business-end" back on. Many button cell lights and other products powered with button cells are prone to having cells go in cockeyed; this is one way to avoid that.

Aren't you glad you didn't kick the "writing" half of the pen down the stairs with all of those hungry, hungry ants now?

Unable to measure current due to how the product was constructed.

Eventually, you'll need to change the pen refill.
I do not know what type or model pen refill this is, so please do not ask.

This instrument is reasonably durable, but because it has a laser in it, I won't do the smack test on it. I know you love to see me break things, but it "ain't" "gonna" happen today, folks.

Water-resistance is minimal at best. When the business-end was suctioned, air had no problems whatsoever passing through it. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of blue whale uranation, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your Laser LED Light Pen to smell like seaweed or piss when you go to use it next. Besides, salt (from seawater or uranation) can't be very good for the insides.

The ballpoint pen portion writes in black ink; and has the writing quality of a very good disposable.

This evaluation look a lot like the one I made for this pen?
Thought you'd say so.
That's because they're similar enough to one another that I could use its web page as a template for this one.

The pen having written the phrase "Is this the correct sysop?".
This phrase was seen on a Commodore 64 computer in the mid-1980s on a program used to set the time.
The word "sysop" though, refers to the operator of a dial-up BBS.

This was actually written with this pen, but both have the same color and quality of writing.
