1997-2001 HID conversion. Only thing missing in that thread is the H7 bulb adapter. You can re-use the old one but drill it out so it sits nicer, or you can ghetter fab the brackets to hold the bulb in.
Another option is to BUY an H7 adapter, where its ready made for you to drop in.
And a nice Projector conversion thread by an old ES300 owner on here: https://www.clublexus.com/forums/es3...o-mini-h1.html
