So I know there are more then a few of us on here with the 599 headlight installed on the 919. I was lurking around some subaru site's a few weeks back looking for some foglight info for my new Legacy daily driver. I stumbled across this info and decided to apply it to my 599 headlight.

The H9 bulb can easily be modded to fit into a H11 housing and connector, the H9 provides better improved light output. The DIY mod will allow you to run a H9 bulb in a H11 housing, mainly the 599 headlight housing.

DIY BULB MOD
Step #1. - Remove the 599 housing from the bucket, mark the high and connectors so you don't mix them up on reinstall.
Step #2. - Lay the bucket glass down on your towel/foam and remove the H11 bulbs from the housing. Wear your gloves and never touch the bulbs glass with your bare fingers, oils can ruin and shorten bulb life.
Step #3. - Compare the two bulb connectors & note the difference.
Stock H11 bulb connector. Has a single vertical ridge between the two connection terminals.
The H9 bulb connector has two ridges between the connection terminals. This second ridge is what needs to be removed to make it plug and play.
Step #4. -The H9's one extra vertical ridge in the center is what needs to be removed. On mine it was the shorter blade, make sure you remove the right one. Just double check against your H11 and mark it, so you don't ruin your new light bulbs.
Step #5. I used the small needle nose pliers to crack off part of the ridge, I then heated my utility knife tip with the torch and sliced off the remaining. Next I then used a small file to carefully clean up the connector surface, and used the pick to pull out any chunks and debris. Blow it out with compressed air or contact cleaner. Test fit it on your headlight harness connector and if it seats fully and securely you are done, just do teh smae process to your second bulb.
Modded H9 bulb before clean up.
Step #6. Install your new modded H9 bulbs into your 599 housing. The three outer locking posts are a touch different and may also need to be trimmed, on mine they just snapped in after a couple attempts and adjustments.
Step #7.Hook up your connectors and reinstall back the housing back into the bucket.
I will hopefully have some before and after pics later on tonight, depending on the weather. From first glance it seems brighter and from all the other H11-H9 info out there it should be close to the same noticeable improvement.
And yes I didn't wear gloves. Haha.
