I'd be interested in the Form 337 for the install.
Or is there a standard STC? Sounds like a homemade solution in a Standard
certificated aircraft.

Jim, I had actually calculated 540 ohms for 13 volts and went looking for
560 ohms resistors. My local RS didn't have any 560's so I settled for
two
1K 1/4 Watts in parallel. Good catch.

If you added 500 ohm resistors to the circuit you've done something no
other human being has done since RETMA took charge of component values
prior to WWII. 470 or 510 maybe?

The one slight mod I did to Jim's schematic was to add 500 ohm
resistors
