2007 Camry SE V6 HID kit help

I just need to know what type of kit I should buy. I know Mccolluchs and Phillips are a good brand. The thing is that I have the daytime running lights and auto on feature for my headlights. I want to know if I install a HID kit that runs off the battery and uses a relay...will I lose that auto on feature? Or should I get the kit that can run off OEM power source?
