I appreciate everyone's help weighing in on my led conversion but unfortunately the solution http://aeroelectric.com/Pictures/Schematics/LR3_LV_Led_1.jpg did not yield a working result.  On the bench the prescribed setup with the resistors and led will light glow with less than 12 volts.  
This is the what I installed using (2) 470 ohm 1/2 watt resistors:

Meter across the leads south of resistors:

The incandescent bulb glows fine when installed, unplug the incandescent lamp and plug the led/resistors into the circuit and NO light.


Please help!
Thanks,
Tim Jennings

Hi Tim,

Sorry to say the photo links still do not work, at least for me. You could attach them to a posting on Aeroelectric List or this instruction might help... scroll to "create a shared album" and "send a link to share".
