This is the 1xD Cell Distress/Marker Light. It has a small screw-base incandescent light bulb in a sturdy housing, and is powered by...you guessed it...1 D cell.

It is designed to be affixed to a life preserver (or "life vest" if you prefer), using the very sturdy and beefy "safety pin"-type fastening device affixed to the side of the product.

Electrically, this product is quite easy to use.

On the side of the barrel, you'll see a slide switch. Slide it up (toward the transparent domed "lens") until it clicks once. Located directly above the part of the switch you move, you'll see a small button. By pressing & releasing this button, you can blink the light on & off (to signal in Morse code, for example).

Slide the moveable part of the switch up until it clicks a second time to switch the unit into continuous-on (or "handsfree") mode.

Slide the switch all the way down until it stops moving to turn the product completely off.

To change the D cell when necessary, unscrew & remove the transparent domed "lens", and throw it over the side of the boat so that it slowly sinks to the bottom and becomes fish food on the way down...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.
If the metal platform with the bulb on it falls out, just drop it back into the domed part, bulb-first.

Tip the used D cell out of the barrel and into your hand, and recycle or dispose of it as you see fit.

Drop a new D cell into the barrel, orienting it so that the nipple-end (+) positive faces out.

Holding the unit horizontally (primarily so that the bulb assembly doesn't just fall off), screw the domed part fairly firmly back on, and be done with it.

Since this is an incandescent product, sooner or later you'll need to change the bulb.
Simply follow these easy steps to accomplish this:
  1. Disassemble the product as you would for a battery change.
  2. On that metal disc, you'll see a little globe-shaped bulb. Unscrew it, and throw it in the dustbin (garbage can).
  3. Screw a new GE #3 bulb (1.5 volts screw-base) back into the receptacle for it on this disc.
  4. Reassemble it as directed above.
Light bulbs are not yet recyclable, which is why I did not offer that option.

This product is meant to be used as an emergency beacon clipped to your life preserver, not a flashlight designed to be bashed, thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a porch, use a small sledgehammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (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), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that a flashlight might have to have performed on it. 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.

In fact, that photograph, spectrographic analysis, and video directly below may be "it".

Test unit was sent by R. (aka. Sigman on Candlepower Forums from Anchorage AK. USA, and was received on 04-03-06 (or "03 Apr. 2006" if you prefer).

Because it was defective right from the get-go, that dreadful "" icon will have to be used at once.
