i just installed new LED signal lights on the front and back of my 03 and this evening they started flashing rapidly. they dont do it all the time but most of the time. i was wondering if the flasher relay under the dash may have something to do with. if anyone can help me out i would appreciate it alot

 

You have to add a resistor to stop it,

 

they been in for a week at least and they just started doing it.

 

Hmm that's weird maybe one of your turn signal bulbs is out on your tail light I would try that
