I don't need it because my EFIS has that feature built in. The yellow LED has a narrow beam, thus it should be mounted so that it is aimed directly towards the pilot's eyes. The LED does NOT flash, but should get the pilot's attention if aimed at the pilots eyes. The LED comes on when the voltage drops to about 13 volts. The voltage of a lead acid battery with a load on it will drop below 13 within a few seconds of charging system failure. The electronic components are surface mounted with E-6000 adhesive to a perf board 24 x 44 millimeters. There are no conductors on the other side of the perf board. So the board can be mounted to a conductive surface if desired. Two pairs of wires exit the circuit board. One pair of wires needs to be connected to a fused voltage source. The LED is already connected to the other pair of wires. The LED can be inserted into a 3/16" hole drilled into the instrument panel and glued in place with E-6000. I will give the warning light free of charge to someone who donates to Matronics. https://matronics.com/contribution/ Oh, and one other condition: After installation, Post a review on the AeroElectric list telling how you like it. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=513644#513644 Attachments: http://forums.matronics.com//files/low_voltage_warning_light_887.jpg ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
