I change mine to LED last week. For some reason my car suddenly won't start after I use it for less that a week. So, I bring it to Mazda. They diagnosed the cars & was told I blow a fuse. It cost me almost $150 to have it fix co'z its not covered with warranty. Also, they remove all my LED lights & install the old (stock) one. All my LED's came from my Mazda 5 that I traded & it's a little bit confusing when they explain it to me of what happen. I am just writing this for you guys to be careful.
