My cruise control will work if my headlights are off but as soon as I turn them on it will cancel my cruise and the set light will start to blink, same goes for if I use my windows. It's almost like a voltage drop is causing the issue, nothing else is wrong with the car.. just this new annoying issue. Could it be my LED taillights?

 

Did the problem start right after you put in LED taillights? If so, replace them with your OEM lights. If everything works correctly, it is your LED lights.

 

Honestly, the car had sat in a body shop for two years and i got the car back and installed them without trying it before hand, am going to switch them out and see if it makes a difference

 

was the LED tails!
