I'm not sure how Mazda was able to get the OK from the IHS or whatever body approves this, but I've seen so many vehicles have to turn off their DRLs when signaling and I'm not sure how Mazda was able to get away with it. I actually saw the other day a vehicle which had completely separate housing located under the headlights for turn signals and it still turned off the DRLs when it was on. Mazda has them both housed in the same unit (even the CX5 only uses incandescent bulbs for turn signals and is less prominent than the CX9 and they still didn't have to turn the DRLs off). It's crazy they're able to get away with this when so many other manufacturers, even ones like Mercedes can't achieve it in the US.
