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.

I see what you are saying regarding the projector. Thank you.

As for the blizzard, one of my lights was dead which is why I needed to change it. I suppose one light is better than none.

Yes, the kit I got was supposed to be High and Low, it has 2 bulbs. Could I post a link for everyone to see it or is that not allowed?

You should post a link, but i think your post count is too low to do it.

anyways.. the reason your high beam is working is because halogen bulbs do not care about polarity. HID does.

That's why you are getting high beam and HID is not working. I said the Yaris has a switched ground.. meaning the on/off switch is on the ground connection and not the positive wire. The positive wire has constant power.
To get your HID to light up, you probably simply need to flip the positive and the negative wire at the ballast and it should work.

Note: if i remember well, the H4 bulb connector has 2 grounds and 1 positive.

This has all been really helpful. Thank you all.

The seller also sent me a video of recommended wiring for the 2 positives and one negative, although I wasn't able to get one of the settings working on my lights, so I kept tooling with them until I was content, with the car on. I was able to get some lights working so I am able to run some errands until the weather is better and spend some time working on it for real. A great suggestion, which should hopefully stop this cold from getting worse.

As for the link. If the post count is too low. They were Xentec Hi/Lo 9003 from eBay.

The only other modifications that I would like to make at this time is to paint the grey panel around the stereo and fan knobs, and possibly the knobs as well. Is there any recommended reading anyone can suggest or a tutorial that still has pictures up?

Thank you YW. I will be sure to let everyone know how the lights go once they are perfect.
