You could do that, but then you're negating some of the advantage of these  
things. There are flashers available for reasonable money for LED taillights.  
Either way will work, though...

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.
