This product is not intended to be used as a flashlight, it isn't a laser, it isn't a test instrument, and for Christ sakes it isn't an R/C aircraft either, so the standard review format will not be used and the product will not be assigned a rating.

INDI-LINK (short for, "INDIcator LINK") is a very unique product that allows one to "see" current flow through just about any circuit with voltage above 0.35V to 22kV (22,000 volts) and currents from 1mA to 10 Amperes AC or DC.

From a message to me (no changes to spelling, grammar, capitalisation, punctuation, or syntax were made):

"Hi Craig, Greeting from Wales, Thanks for your help in promoting my Indi-Link product and of course you have my permission to use the video footage on Youtube.( I need all the help I can get) I am painfully aware though that they aren't very good examples and I in my inexperience come over as a bit of a bumbling amateur. I am not shy of my contact details being available to those with a definite interest in manufacturing and profiting from its commercial exploitation either, I shall leave it to your discretion as to who is worthy of this info.

My background is in the North Sea OIl and Gas Industry and in Industrial automated systems in hazardous harsh environments. In these environments we cannot expose any powered electrical equipment because of the risk of sparks causing explosions. We also have a lot of failures due to the corrosive atmosphere offshore. Making whats working, as this thing does. helps you visualise and gain confidence in these systems, look at the Deep Water Horizon accident, can you believe that it was not obvious that there systems weren't working properly? but that is a hugely common scenario. Electrical systems have the habit of failing when demand is placed on them, the light signals, through windows or fibre optic pipe make an easy interface for us technicians to see whats happening all the time, come rain or shine, day or night, without having to touch anything just by looking.

I should say I was a Technician, 2 years ago I was injured in a work related accident in which a severely broke my ankle, this has left me with a limiting disability for which they will not allow my return to offshore work, my only hope now is to sell this Idea to the world but so far have only managed to get a Silver Medal from the biggest Invention Fair in Europe. Other than that nothing. I'm a bit pressed for time at the moment but I shall send you some more in the way of contact information and documents that may find interest, a talk on the phone wouldn't go amiss either-

How to be able to see electrons working in any electrical circuit and by simple reliable means. Electrical current flow in a circuit reflects the circuits working condition. Turning moving electrons into photons greatly assists in troubleshooting the actual working conditions within wiring, Michael Faraday dreamt of what INDI-LINK can do !

Novel control and signalling of a remote valve over just a two-wire circuit. This scheme also lends itself to double or triple wiring for the ultimate in redundancy without the complication that is normally associated with point-to-point control wiring architecture. Note the scheme also includes a display of the valves functional condition both locally and remotely, this is enabled by INDI-LINK Technology, a novel wysiwyg function.

Indi-link as a line powered current detector monitoring the functional sate of an Emergency Stop circuit without a third wire and rendering important visual information to the operator as to prevailing state. Both LED's lit which indicates sevice on an AC current, given that both possible polarities of current are displayed albeit modulated at mains line frequency.

LED current detector that works at any voltage above 0.35 Volts to 22 kVolts and from 1mA to 10 Amperes AC or DC. Get to see whats working in your circuitry, give vision to your mission and make life simple. Then you only need your eyes as test equipment

the audio quality isn't really all that great as a result!

Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at

Please visit this web page for contact information.

Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
