Most vehicles do use the high beams as DRLs, but for whatever reason, this Mazda 5 uses the low beams, at full voltage. I was looking at an 05 and 06 Mazda 3 a few years back, and the 05 used the low beams, and the 06 used the highs at a lower voltage. Figured all the Mazdas with projectors would have changed the same time. I currently have LEDs ordered along with a DRL relay that will reduce the voltage of the LEDs when the headlights are turned on. They will be on all the time the car is running. Planning to disable the factor DRLs when I do the install.
