You should try the All Star Kit mentioned elsewhere here. If you want HIDs, then you will be disappointed with the H9. It just gives you more of the yellowish halogen light. You don't get that white blanket of light that xenons give. Plus you'll be replacing the H9 bulbs very often. Their life is a fraction of a normal H11. So if you're gonna go that route, buy a 6 pack
My Accord now looks like an Acura or Lexus or BMW or something. <$100 for the All Star Kit, plus $10 for some LED replacements for the license plate lights and all interior lights.
Just try the HIDs if that's what you want. Don't listen to the naysayers on here who tell you the only CORRECT way is a full projector retrofit. They are technically correct but PRACTICALLY-speaking our projectors are fine for swapping in the HID bulb. They are worried about the last 1% of perfection. I am happy with the 99% of HID goodness that I have without spending a lot of time and MONEY to get that last 1%.....
That's funny. Your so called last "1%" is what allows proper HID projectors to shine light far
down the road, and wide
down the sides - not down, directly into the foreground, right in front of you, as the optics of the halogen projectors are designed to do. Since you claimed in the "all star" thread that you don't do a lot of night time driving (let alone, be far from home), I would suggest you not make bold statements about "practicality" that could at best prove to be unhelpful, and at worst, be a serious detriment.
I can tell you, from personal experience, that your money saving "all star kit" is a hazard in poor weather conditions - not to mention just general night time driving on completely unlit roads, where your own headlights are your only (blinding) source of light. Try to see if you can find the white dashed lines when it is pouring rain, or in a blizzard, on a highway with other drivers, who also share your sentiments to mismatch HID bulbs and halogen reflectors/projectors. Hopefully you didn't get the bright idea to put in color matching HID's or non-functional LED's in your fog lights when driving in those conditions either.
It's comical you mention replacing the H9 bulbs often - I'm at the 3 month mark and both bulbs are still holding up fine. At $6-7 a pop, per bulb, they aren't really cheap, but it's not exactly going to put you in the red either if you have to change them out once or twice a year. Sure the OEM rated lifespan is quite low, but you are also depending on your aftermarket HID bulbs to hold up to the OEM spec'd lifespans as well. Whether if you trust them that much is entirely up to you, but I would certainly put my money on the likes of Philips or Sylvania/Osram then... wait, who makes TRS's bulbs again?
In the end, a true HID kit is more than just a pretty flood of white light, and a cutoff line. Your kit may look like it came from an Acura/Lexus/BMW, but it certainly does not perform
