I had the same problem on my trailer with regular bulbs until I had the dealer reflash the ECU to recognize the trailer. All was fine for 2 years until I decided to try LED light replacements, and they flash fast again. Different current draw.

mgbmwx5- I'll have to give those resistors a try. Did it slow the blinker or brake light response time?
