Adding L.E.D. bulbs

Hello everybody, I have a 2008 coupe & I installed L.E.D. tail light bulbs [not cheap crap] now the turn signals blink really fast [front & rear] . Has any one had this problem?  

HAVE YOU TRIED A HEAVY DUTY FLASHER ?

You need to install resistors to slow them down.  Google led resistors for turn signals.  Careful where you mount them. They get very hot.
