I am manufacturing a fiber optic instrument post light for experimental aircraft (working on a PMA and STCs for certified planes, but it may be as much as a year before the paperwork is all done and approved). I have had a set of them in my KR and they are working great. They light up each instrument individually like the Wheelen post lights, but they use a central LED illuminator that only requires one power connection for a whole panel of lights and the total power draw is only 30 milliamps.
You can get more information on my web site at www.engalt.com/aviation.htm You can purchase them from Aircraft Spruce. They are currently in stock. The link to the page on their site is http://www.aircraftspruce.com/catalog/inpages/instrpostlite.php For the next 30 days I will give a 10% rebate to any KRNet members. Just email or mail me a copy of the invoice and I will send a rebate check. I am getting additional distributors, but I will not be selling any systems direct. Please send any questions to me at br...@engalt.com, not to the list.
