I do respect Rhino_66's directive not to make this into a DRL debate and I'm glad he gave us the Mazda procedure to disable DRLs for owners preferring to do so (the purpose of this particular thread).
Related to discussion about DRL's (answering above question and not wanting to start a debate) and the "why's":
. DRLs are not required by law in the US.
. Studies showing improved safety resulting from DRLs are questionable and sources possibly biased.
. Many motorcyclists would prefer 4 wheeled vehicles to not have DRL's, that way motorcycles with required (US) DRL's would stand out better for improved safety (versus being in a sea of DRL-equipped cars and therefore motorcycles not standing out). Haven driven in Canada and seen what it's like to see virtually all cars running DRL's, and resulting saturation.
. The dim yellow lights of common DRL's are not attractive to some, many prefer the Audi-style white LED DRLs from a styling perspective.
. Notes: Some GM light trucks have override/off switches for DRLs, upon restart the DRLs function normally (default). Mercedes cars (US) make the DRL function driver-selectable via simple menu. CX-5 DRLs are not good "parking lights", they turn off when car is in Park.
