TURBOFLARE 360 LED EMERGENCY LIGHT

[moe]

Hello
Has anyone looked into this light or have info to build one? I have some LED's here and would like to build a light of this type.I have seen these on the road and they work well. The site is http://www.truckersmall.net/360turboflare.html
Thank you
Moe

From the picture it appears that there are 8 LEDs arranged around the circle, which are lighted one after another. All you need is a "LED chaser" circuit and some packageing. But, for $22.95, I don't think you can build one that cheap.

You gotta be kidding....a couple of ultrabrite leds, a 555, and a 4017 will produce the same thing...probibly better.

or about a million other schematics found when Googling 4017 led chaser schematic.

initially, I thought the posting was spam because the web page it pointed to is pretty ridiculous. I can't believe that is a reasonable deal.

A couple years ago I saw these at Sam's Club but I thought it was $25 for a two pack. Still I thought that expensive.

The LED chaser circuits are standard fare and others have linked the schematics already. Super Ultrabright LEDs, especially the red ones, can be had for pennies from eBay vendors and elsewhere. Places like http://www.allelectronics.com sell weatherproof third brake lights for about $7 with 12 LEDs. But let me throw this suggestion out to you.

There are plenty of Christmas controllers that perform all sorts of neat functions. A string of motion lights can be purchased for under five bucks on discount sales. You might even have a "bad" string of lights where the controller still functions but the lights have issues. I'd suggest sticking with the motion style where there is only a speed control instead of all sorts of functions. While on the issue of Christmas lights you might also purchase a string of LED Christmas lights that have shown up for sale in the past few years.

The controller uses a voltage divider resistor network and full wave bridge to get the low voltage DC. Remove these and the circuit should easily work on two or four batteries. Drive two opposite LEDs with the four circuits off the Christmas light controller. For a case a simple "Tupperware" bowl would work nicely.
