Do you have an Auto position on your light stalk? If you do, that will turn on your drls during the day, and lowbeams at night. SCH-I535
The PC doesn't have auto headlights. ... At least not in the US. Maybe Canada is different, but I don't think so.
Why do you want to turn it off? mandatory in Canada so I removed the halogen light and use cheap led as running light. I have hid for low beam so I don't really need high beam.
The odd thing now, at least in BC, there's a LOT of late model cars and trucks on the roads, with BC plates and no DRL ;(
