HALLOWEEN LIGHT-UP
SKULL NECKLACE

Halloween Light-Up Skull Necklace, retail $1.99 (www.wallgreens.com)
Manufactured by (Unknown)
Last updated 10-31-10




This is a flashing skull LED necklace designed to be used around Halloween (October 31 in the USA). I purchased it not because I really wanted one, but because of those LEDs in it.

It goes around your neck with the included break-away lanyard, and when activated, flashes the LEDs inside for approximately 16 seconds.

I was not able to locate the URL to the page on the Wallgreens website this product is on (if it's on there at all!!!), so I was not able to furnish one.


SIZE



This product comes in a simple plastic bag; just remove it from the bag any way you see fit, dispose of or recycle the bag as you see fit, and hang the skull around your ne--o wait, see directly below for that part.

Place the necklace - where else - on your neck.

Press and release the small grey button on the bottom of the skull; the LEDs in it will come on and flash in a predetermined sequence for approximately 16 seconds, then automatically extinguish.



To change the batteries when necessary, use a knife, pen, or other pointed instrument to pry the white plastic thing out of the bottom of the skull. Set the skull portion aside.

Push the battery stack out of the open-end of the battery carriage. Remove the used batteries from the plastic collar, and dispose of or recycle them as you see fit.

Stack three new AG-10 button cells on a desk, table, counter, or other flat surface, flat-end (+) facing up. Lower the plastic collar over them; gently push down on it if it feels a bit stiff.

Place the collar/battery assembly back in the battery holder, orienting it so the flat-end (+) faces up.

Insert the white plastic thing (with the LEDs and batteries on it) back into the skull, so the side with the LEDs and batteries on it goes in first. Press it along its edges to be sure it goes all the way into the skull.

Due to the way the product was constructed and how it functions, I am not able to furnish a current usage measurement for you.



This product is meant to be used as a necklace on Halloween, not as a flashlight meant to be carried around, thrashed, and abused; so I won't try to flush it down the toilet, bash it against the corner of a concrete stair or against a steel rod, let my housemate's kitty cat's ghost go to the bathroom on it, run over it with a 400lb electric Rascalator thing, or perform other indecencies on it that a regular flashlight might have to go through. So this section of the web page will be significantly more bare than this section of the web page on a page about a flashlight.

The cycle time of this product is approximately 16 seconds.

TEST NOTES:
Test unit was purchased at Wallgreens on 10-13-05 at a discounted cost of $1.50.

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.


UPDATE: 10-31-05
Of course, a Halloween update for a Halloween product.
I used it while I was away from home late this morning, and I intend to use it this evening when handing candy out to Trick-Or-Treaters.
