Thuh kompanie thaat maiks thuh Nite Writer II kant spel thuh werd "night", but they still make an excellent product.

This LED-lighted ballpoint pen, labelled "Nite Writer II" on the barrel, is a ballpoint pen in a plastic body, that features a yellow-green LED near the writing tip.

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


Press the button on the top of the pen until it clicks and then release it to activate the LED.
Do the same thing to shut off.

To write with the pen, remove the cap, and write. It writes in black ink, with the quality of a very good disposable pen.
Place the cap back over the end when you're finished using it.

To change the batteries, unscrew and remove the upper portion of the pen, take it 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 barrel and into your hand, and dispose of or recycle them as you see fit.

Insert two new L1154 button cells into the barrel, orienting them so that their button-ends (-) negatives 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.

Current usage measures 24.70mA on my DMM's 40mA scale.

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.

Yellow-green LED illuminated.
The writing you see ("SYS 64738") reboots a Commodore 64 computer when you type "SYS 64738" and then hit the "Return" key. This functions like executing the command "JMP #$FCE2" in an assembly language monitor on the same computer.

Unit was found in my stuff on the morning of 08-15-09.
I believe I obtained it sometime between 2003 and 2004.

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.
