Blue LED Flasher, retail $TBA

Last updated 05-19-10

This is a fairly small flasher (warning light) that is designed to be affixed to virtally any motor vehicle -- though they can also be used to liven parties up if desired.

It operates on DC (direct current), at a voltage of +12 volts.

It uses a ring-shaped array of 20 high-flux LEDs that have a flash rate of 12 FPM (flashes per minute); this is 0.20Hz (1 long flash every five seconds).

Although I believe you're supposed to be able to easily mount this somewhere, I do not see any means (convenient or otherwise) to accomplish this. Best guess here is that there are one or more components missing.

Connect the black wire to (-) negative, and the red wire to (+) positive of any 12 volts DC source (this will often be a vehicle's battery). No on/off switch is furnished; you'll need to procure that elsewhere. Connect it between the positive (+) voltage source and the flasher's red wire.

This product is designed to operate on +12 volts, not batteries, so I do not have to tell you which part to remove, gently place on the floor at the top of the basement stairs, carefully push over the side with your foot so that it clatters down to the basement full of piss ants with full bladders, and then rather emphatically tell you not to.

This is a vehicle flasher, not a flashlight meant to be bashed, thrashed, trashed, and abused; I won't throw it against the wall, stomp on it, try to drown it in the toliet bowl or the cistern, run over it, swing it against the concrete floor of a porch, use a medium claw hammer in order to smash 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 flashlights may have inflicted upon them.

So this section of the web page about the Blue LED Flasher 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 you see directly below may very well be about it.

This is the product in its "on" cycle.

Test unit was sent by a fan of this website and was received on 03-22-06 (or "22 Mar. 2006" if you prefer).

As far as I'm able to determine, this product was made in the United States.
A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 00-00-00

Bright, attention-getting flashes
Uses LEDs that should have a very long life
Unique deep blue color is achieved without the need for filters
Appears to have extremely durable construction

Slower than desired (0.20Hz) blink rate (this is what nocked that last star off) -- I would have preferred a 1.0Hz (60 flashes per minute) minimum blink rate
