This LED-lighted ballpoint pen, labelled "HEATH RASCAL SVC" on the barrel, is a ballpoint pen in a plastic body, that features a red LED deep inside the pen body that shines through an acrylic piece to illuminate the area around the writing tip.

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


Turn the top of the pen clockwise until it clicks to activate the LED.
Turn the top counterclockwise until it clicks to shut it off.

To write with the pen, grasp the blue portion of the barrel with one hand and the transparent part of the barrel with the other, and twist clockwise. This extends the writing part of the pen. It writes in black ink, with the quality of a very good disposable pen.

To retract the pen tip, grasp the blue portion of the barrel with one hand and the transparent part of the barrel with the other, and twist counterclockwise. This retracts the writing part of the pen.

To change the batteries, grasp the blue portion of the barrel with one hand and the transparent part of the barrel with the other, and twist counterclockwise. Twist with a bit more force than you would use to retract the pen tip. Unscrew the two halves; being certain to hold the pen rightside-up when you do this. Take the top half (the blue part) to a bridge over deep water (the Golden Gate Bridge would be ideal; however, the Juneau-Douglas Bridge would also suffice here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the used button cells out of the translucent battery holder and into your hand, and dispose of or recycle them as you see fit.

Insert three new LR41 button cells into the battery holder, orienting them so that their flat-ends (+) positives go in first.

Screw the pen's top piece back on, and be done with it.
Aren't you glad that you didn't throw that pen top piece over the side of the Juneau-Douglas Bridge now?

This is what the Jueau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.

And this is what the bridge looks like now.

This is a pen meant to be used as a pen in a dry area, not a flashlight meant to be thrashed and abused, so I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a porch, bash it open to check it for candiosity, fire it from the cannoņata (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser- (or "lazer-") type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoņata is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that I might inflict upon a flashlight.

So this section of its web page will be rather bare, when compared to this section of the web page on a page about a flashlight.

The pen is not water resistant, so a concerted effort should be made to keep it from falling in the toliet or drowing under your lawn sprinkler. If water does get in, just open it up as best you can without tools and dry out all the parts, and it should be fine.

The pen portion seems to be on par with any of the more expensive disposables available, and it writes with black ink.

Red LED illuminated.
The writing you see ("SYS 44444") generates a "?SYNTAX ERROR" message on a Commodore 64 computer when you type "SYS 44444" and then hit the "Return" key. This functions like executing the command "JMP $#AD9C" in an assembly language monitor on the same computer.

Spectrographic analysis of the LED in this pen.

Unit was found in my stuff on the morning of 08-16-09.
I believe I obtained it sometime in 2005 when Joe Heath came over to examine my Rascal #255 scooter/electric wheelchair conversion for a vexing power drain problem.
