I am sure some other ecu changes would need to be made but is there anything else I'm missing? I'm sure there is, I am thinking of doing it myself, so it would be good to know
You either gotta do it all OEM, or wait for some company to do a self-contained aftermarket version. You can't just piece together the housing plus some bulbs.
You need an OEM assembly for each side ($900 each), the control modules plus the LED/Xenon bulbs, that's another $1K for each side. So now you're almost at $4K before any labor cost or coding. And no one knows how to code it yet, so you'd be pretty much stuck.
Here's the parts you need. Have at it
And we're expecting a thorough DIY write up if you succeed.
