I had to have my entire set of P46's sent back to DDM within the first month of owning them because all 4 rings had 3-5 dead leds in the middle of the rings. They initially didnt want to but I made a stink on the forums and combined with pictures and the fact that they were brand new there was nothing they could say but yes please and then some. I would caution with LED's though as I'm on my third set of LED tails with Khoalty (great guy and business) for LED "issues". I honestly dont know if the car hates LED's or I have bad luck but I have never had to RM stuff some much in my life!!!
