Not without some rewiring and such. IMO the DRLs are too bright/unfocused to run at night, they will really bother other drivers. A few other threads on this: 2012 DRL's on at night? | PriusChat 2012 Prius daytime running lights | PriusChat
I didn't think the DRL's are that bright to be annoying to oncoming drivers... but i guess at night its different than the day time. Oh well.. i guess ill just install OEM fog lights and call it a day. Thanks for the links!
You can buy a drl relay that dims the drl at night once you turn on your headlights. But it requires rewiring them. SPH-L900 ? 2
