I asked my Dad (a biomedical electronics technician) about this becuase my friend had problems in his camaro. My Dad felt that the problem was because LED's draw so much less current. He was supposed to tell me a way to fix it, but I forgotten to ask him about it. Anyways, I think that if you were to wire a 1/2 watt resistor in parallel, then the blink rate would slow down. The resistance value for the resistor shouldn't matter, since 12V will still be supplied to your turn signal LED's. No guarantees, but that's what I believe should work.
