I have an 08 and just installed a pair of LED turn signals. I have read a lot about hyper flash and my truck seems to be doing the opposite, they flash regularly but all of the cabin lights flash with them. I am not sure if this is a resistor situation or not. I have heard of people replacing the flasher under the dash, but that may knock out cruise control. Any and all feedback would be greatly appreciated.

 

Well after all hyper flash seems to have reared its ugly head. So I am going to try the Novita EP27 route as per recommended on the You Tube video. They suspect that it may cause problems with the cruise control though. I'll let you guys know.

 

Didn't work... so when I turn my all my lights on they work fine. When I turn my lights to any other setting all of my cabin lights flash.... any suggestions? Now this may be a dumb question, but do I have to have led heads and rears for them to work properly? This is driving me nuts.
