The SerpentLight is a handy-dandy little flashlight that can be used in three distinct ways:

1: It can be fitted with its flexible gooseneck and clipped to or attached magnetically to an appropriate surface to light up tight little spaces when you need both hands free.
2: It can be fitted with the stubby (short and inflexible) illuminator head and subsequently be used as you might normally hold & use a small flashlight.
3: It can be clipped to the brim of a baseball hat and be used as a "headlight" if need be.

It comes in a predominantly all-metal body, has a magnet on its tailcap, has a pushbutton switch on its barrel, has two colors of LED (blue & white; usable seperately only), and feeds from three AG-13 button cells.

It's called the "SERPENTLight" probably because it has a flexible metal gooseneck that could remind one of a baby garter snake.


The SerpentLight needs to be fed its included batteries first (see directly below), and THEN you can go find what's making that squeaky noise behind the toliet.

Very firmly press the little button on the barrel and then release it to turn the unit on.
Repeat this action to turn it off.
I say "VERY FIRMLY" here because this button requires significant pressure to actuate and deactuate.

Momentary (signalling) mode is available by pressing the button less firmly and holding it that way for as long as you want the light; release the button to turn it off.

The SerpentLight comes with the gooseneck illuminator already attached; you may affix the light to your work area in two ways:
1: Use the "alligator clip" on the product's barrel to clip it to the edges of surfaces up to 0.4" (10.0mm) thick.
2: Stand it on its magnetic tailcap to any magnetic (iron, mild steel, nickel, cobalt, or gadolinium) surface.

You can also clip it to the brim of a baseball hat, as shown directly below:

To change the illuminator heads, simply unscrew the head you want off until it comes free, and screw a replacement illuminator head in place. It's pretty intuitive once you do it one time, maybe twice.

The insulating washer on the underside of the head is colored to let you know what color the LED is without your having to guess; eg. the white LED heads have a white insulator, and the blue LED head has - you guessed it - a blue insulator.

To change the batteries, unscrew & remove the tailcap, gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy for their little insect tummies and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the three used AG-13 button cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Insert three new AG-13 button cells into the barrel, orienting them so their button-ends (-) negatives go in first.

You can also stack the three AG-13 cells on a table, counter, desk, or other flat surface with an edge; button-ends (-) negatives up. Lower the body of the SerpentLight over the cells, and slide it to the edge. Place a thumb or finger over the barrel so all of those brand spanken new batteries just don't clatter all over the floor, and invert (flip over) the SerpentLight and your thumb or finger simultaneously (at the same time). Remove your thumb or finger from the light when the opening of the barrel faces up.

Finally, place the tailcap over the opening and firmly screw it back on.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry, hungry praying mantids now?

Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

Current usages measure 44.8mA (white LED) and 49.2mA (blue LED) on my DMM's 400mA scale.
This is a fairly high load to place on those tiny little button cells, so battery life may not be as long as might be desired.

After ten firm whacks against a concrete sidewalk (five on the side of the tailcap and five on the side of the bezel {when one of the short illuminator heads was attached}), no visible damage was detected. No optical or electrical malfunctions were detected either.
This wasn't entirely surprising considering the small size of the product; I was not able to whack it quite as hard as I might whack a larger flashlight.

There are no environmental seals (O-rings) visible on it, so is not all that water-resistant. Therefore, water, milk, diet vanilla Pepsi, cold (or hot) coffee, urine, ice cold fizzy root beer, disposable douches, disposable enemas, or other liquids could get inside. So please try not to drop it into creeks, rivers, ponds, lakes, oceansides, docksides, snowbanks, puddles of albino lab rat pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee (hot *OR* cold), fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, leaky water heaters, busted garden hoses, puddles of antifreeze, brake fluid, tranny fluid, gasoline, or other places where water or water-like liquids might be found. And you'll probably want to cover it up or otherwise get rid of it (such as by putting it in a pocket or bag) if you need to carry it in rainy or snowy weather. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in lightly to at most moderately bad weather.

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, got thrown into a glass of milk, if it fell in a root beer float, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something peed on it, rinse all the parts out with fresh water before setting them out to dry. You don't want your SerpentLight to smell like seaweed, sour milk, flowers, fresh butts, or rotten potty when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or urination), lactic acid (from moo juice), or sugar (from root beer & ice cream) can't be very good for the insides.

There are holes in the side of each illuminator head; these allow light to "leak" from the sides.
If you find this offensive, bothersome, or otherwise unacceptable, it is easily remedied with the application of a bit of black electrical tape - just tape over the holes in the side of the bezel.

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.
