So, I just replaced all of the rear lights to my truck listed above z71 diesel with LED lights and all the lights work but i keep getting the rear turn single failure. it blinks 3 times normal then does a rapid blinking. what should i do to correct this problem? i have tried cleaning out the bulb inserts with contact cleaner.

Yes, you must get the bulbs with the built-in resistor, or you will have this problem. Here they are on Amazon for $28.00:
