And this is your option having spend the money and looking to justify it, rather than actual fact. You have now made many parts of your car non-functional, made your car a hazard to others on the road, and to some degree even REDUCED your night time visibility.
Lows - We've known since 2005 that the various WRX halogen projector headlights work poorly with HID kits. They do glare (a good amount too) and they beam is not consistent and even as a proper HID optic would have and the brightest point in the beam is not at the cut off, where it should be. This hurts distance vision.
Highs - If you intent to leave them on long term, then no harm no foul. However you have made it so you can no longer flash your lights or use the, short term. HIDs require up to 30 seconds to fully warm up. Repeated use without allowing them to fully warm up is a great way to kill a set of HIDs. You can't flash them and you can't use them short term. This is why bi-xenon HIDs exist as an alternative to independent HID highs.
Fogs - Your foglights are now completely useless in poor weather because they now emit too much light. They are just going to send up a wall of light in fog that will hurt your and other driver's vision due to light refracting and reflecting off fog/snow/rain. Not only that, but in clear weather, brighter foglights are bad
for night vision. Sure you can see better for about 20 ft, but at any road going speed (+30 mph) that's not far enough to see anything to avoid. The problem is that your eyes try to adapt to use the brighter foreground light and this is done at the expense of your distance vision, which is what matters most. You're not even supposed to have them on in clear weather with the stock halogen bulbs. Not to mention that nothing glares more than a set of small foglight lenses. Everyone around you is getting a face full of HID.
