By the way, here's the calculator for determining LED resistors:

Hi John,
MANY thanks for all of us on this good  info.  As for the issue of the 
flasher, which will not work at the lower  current, why not just wire up a resistor 
to ground to force more current  through the flasher and it should work fine?  
This could be mounted right  next to the flasher under the dash.  I realize 
it hogs and trashes  current, but with the LEDs not being very subject to 
burnout, the non-flashing  "feature" for a burned out lanp is no longer needed.  I 
would need to  figure out what the required resistance and wattage would be, 
but it should  not be difficult to measure the nominal flashing current on a 
stock system,  then measure the current drain with the brakes on and the flasher 
not working  right, then just calculate the needed current differential at 
about 14 volts  and viola, you have the needed resistance to add under the dash. 
 The  wattage would be 14 squared divided by the new resistor and then throw 
in a  derating factor of 2-5X added wattage for longevity.  The resistors 
would  be different when running LED side lamps in addition to the rear  
turnsignals.
