LED Cap Light, retail $9.99 (www.target.com*)

Last updated 07-15-09

This is a light designed to be clipped to the brim of a baseball hat.

It has three 5mm white LEDs, and feeds from two CR2032 lithium coin cells. It comes in an all-plastic case, colored black.

* Not found on the Target website, so this URL simply leads to their front door.


To use the LED Cap Light, just slide the unit over the brim of a baseball hat as shown in the photograph directly below (there are two "clips"; push it onto the brim of the hat so that the brim goes between the two):

Photograph of it clipped to the brim of a baseball hat.
I'd have normally used a "Phoam Hed Phred" (styrofoam wig modelling form) for this photograph, but my parents forced me to throw it in the dustbin (garbage can) in December 2008 prior to us moving from Sacramento CA. USA to Federal Way WA. USA around New Years Day 2009.

The unit pivots in the Y-axis (vertically); the range of motion is ~165°; this allows you to direct (aim) the light pretty much anywhere you need it.

To turn the light on, press & release the button located on the upper surface of this product near the right front.

Press & release the button again time to turn it off.

To feed the Cap Light, turn the unit upside-down (so that it curves slightly upward at the edges). Lift the clip assembly up (it is on a hinge). Slide the battery door off, 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.

If necessary, remove the two used CR2032 cells from the compartment and dispose of or recycle them as you see fit.

Install two new CR2032 cells, orienting them so the cell at the front (closest to the LEDs) goes in flat side (+) down, and the cell toward the rear goes in button-side (-) negative down.

Slide the battery door back on until it snaps into place, swing the clip assembly back down, and be done with it.
Aren't you glad that you didn't throw that battery door 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 60.20mA on my DMM's 400mA scale.

This is an all-plastic product, and there are also no environmental seals (such as O-rings) visible. 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 front porch, use a medium claw hammer to bash it open in order 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-type device on a platform with a large readout (located at Piņata Central), a handheld wand that Langston Lickatoad uses, or a pack-of-cards-sized instrument that Fergy Fudgehog uses; and the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it crashing into a quantum filament
*, send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that a flashlight in a metal or sturdier plastic body may have inflicted upon it.

So this section of the web page about the LED Cap Light will appear ***SIGNIFICANTLY*** more bare than this part of the page about a sturdier, barrel-style flashlight.

Those colored graphics toward the left are my "Viva Piņata" posters, and that clock on the right that looks like a gigantic wristwatch is my Infinity Optics Clock.

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.
