Went to my Mazda dealer this afternoon trying to find out the 2016.5 inventory. I checked a 2017 CX-5 Touring on DRLs. There's a white light between inner amber parking light and outer projector LED headlight. I assume that white lights in between are DRLs for Sport and Touring. These in-between low intensity white LED lights apparently wired like those halo LED Signature DRLs on GT. Not sure if the headlights would be on as part of DRLs if the car is moving.
Should have taken photos and posted here
