Just did the H11 to H9 conversion myself on my Impreza. Picked up a pair of German made Osram bulbs from Canadian Tire at $13.99/ea.




New H9 65W halogen on the left (driver side) and factory H11 55W on the right (passenger side).
It definitely looks brighter with a wider beam pattern and larger hot spot. There seems to also be a little bit more glare above the cut off but I don't think it's very pronounced so I'll probably leave my headlight adjustments as-is.

Fun story, purchased a used WRX a while back and the previous owner installed/hacked in an HID kit. Not interested in keeping this setup so itís going in tomorrow to have stock wiring harnesses put back in. Any issues with installing H9 harnesses instead of H11s?

I've had my current H9 bulbs in for years, still going strong. I did clean the bulbs off with alcohol before installing them this time, even straight from package there was grime on them. Any dirt or oil on them makes them wear out or fail early. I didn't use the harnesses I bought either, I just shave down that one flange in the plug and they fit in stock harness. The harness adapter works fine though.

I have a 2012 Subaru WRX Sedan with the OEM halogen headlights (projector style low beams). The H11 to H9 mod seems simple enough I think. Can someone provide me a link to which H9 bulbs are recommended the most, and a link on how to modify them if needed? Or a link if a special harness is needed or otherwise?

Thank you!!

Go to any parts store. Buy a pair of standard/OEM grade off-the-shelf H9 bulbs, NOT Silverstars or anything with a blue coating. Compare them with the H11's, when you look inside the connector on the bulb you'll see a tab in the H9 that's not in the H11. Snip those tabs off (it's easiest with a small pair of flush cutters that can reach inside) then install the H9's directly in place of the H11's. That's it. No mods to the car wiring or lights needed.
Keep the H11's in the glovebox as spares and note that the H9's do have a shorter rated lifespan than the H11's, although with that said I did this mod four years ago and I'm still on the same set of H9's.

I got my bulbs and the metal flanges are a different shape. I do not understand why this is not being discussed. Did the flange shape change from 2012 to 2019.

Trimming the plastic plug is easy. Cutting metal next to glass (that you cant touch) is a difficult procedure.

Does anyone have guidance on this issue?

You'll need a small pair of snips to snip the metal if the bulb doesn't lock in.

I never posted about this but I will now. The first set I had I did not touch, very careful not to touch them.. Well they lasted about a year or maybe 18 months.

Next set I said screw it, I am going to clean them myself with isoprpyl alcohol and microfiber then hit them with compressed air to get any microscopic lint off of them.

Now it has been several years and they are still going fine, and I got a TON of crap and dirt off of them right from the box! They are absolutely filthy dirty out of the box. Must be a dirty factory or something. Or maybe they don;t care or maybe they do it on purpose to deliberately shorten the lifespan. Whatever reason, clean them yourself.. Touch them all you want, then clean them right before install and don't touch them after last cleaning.

So quick follow up.

After trimming the smaller inner tab with a dremel and trimming the metal flange/base with small metal snips I was able to install the bulbs.

The verdict. Headlights are now both brighter and whiter. I can now tell when they are on. It was worth the trouble. The vehicle is now safer.

Recommendations: do the mod. Buy the bulbs online (I got mine in store so cost me $50) use a dremel and metal snippers

Yup it makes low beams actually usable! I got mine for something like $8 each at Autozone last time I think. They were really cheap.

Also now you can easily glare people with your low beams a lot worse if they are too high so you have to make sure they are adjusted well..

But I almost don't feel bad about glaring people anymore, seems like everyone has those "self leveling" leds or hids that blind everyone even on low beams.
