2008 Yaris HID Install, help with wiring. - Toyota Yaris Forums

Your OEM headlight bulb is dual filament, one bulb that functions as low and high beam. The HID bulb is not dual filament. It cannot be used for low and high beam.

Are you just putting an HID kit into your headlight housing without a projector? HID bulbs are not designed for reflector housings. It is often frowned upon because the dispersed light can be a nuisance to oncoming traffic. You need a projector made for HID to house the HID bulb for correct light refraction. You'll need a bi-xenon projector for the HID to function as low and high beam.

I suggest you putting everything back to stock for the blizzard so you can drive without worrying. When the weather improves, you can work on your car again.
