Also got mine from DDM tuning.
I've since replaced them with ballast-less M1 LEDs from Evitek. The high beam pattern and throw are just as good as HID and they're instant on. The low beam has great cut-off, so no blinding oncoming traffic, but the light is scattered side-to-side and I don't get enough reach. May go back to HID on the low if fiddling with aim and the installation depth doesn't fix it.
Here's the
Evitek site. They list H4 here but also have H1 and H7 M1s. The transaction (Cindy link) is via Alibaba, so you may not want to open that can.
