Actually built my own since I couldn't find anything that I liked and I'm too cheap to pay somebody $300 - $700 or more for something I can do myself for ~$250 in parts (at the time) over a weekend. Obviously, much more now.... As detailed below most all parts are still readily available on the internet/ feebay. May need to look for awhile to find the best deals however.
I started with a generic set of replacement lights; think they cost me ~$50 at the time. I used a standard heat gun and small pry bars/screwdrivers to separate the lens cover from the body. Actually, not too difficult once you get it started. Next, using a couple of kits you can buy (on feebay); Projectors; Headlight Retrofit mounting kit and screw kit mount the projector into the back of the reflector. Sorry I didn't do step-by-step pics.

Pic #1 - Body of light Completed reflector
Completed reflector body w/projector and LED switchback surround.
I added the LED switchback surrounds wiring them in place with fine copper wire and installed the assemblies back into the body of the light.
75% completed
Next, I ran the wiring for projector controls and LEDs out the bottom of the lights thru rubber grommets I picked up at Harbor Freight.
To get the lenses back on just heat up the butyl sealer with a heat gun for a few minutes and clamp together well with some plastic clamps. Again, not difficult to do. Just ensure you have enough to clamp all the way around the lens seal.
Finally, I installed them back into the car using pre-made two-wire connectors by soldering and heat shrinking all of the wiring after interfacing it with the front turn signals and lighting circuits. After some testing pronounced everything good to go. The two white strips are SMD turn signals that I added but haven't hooked up yet as the switchbacks are doing a fine job in that regard. Apparently, I've reached the limit for what you can upload in one message so will need to create another message if you're interested in wiring details on the car side and seeing them operational.
Overall, at least IMHO I think they look and perform as good/better than most anything you can get on the market. I also added projector specific bulbs that really make a difference in the light output performance of these projectors.

I'd keep looking; Oracle is too expensive. I believe I paid $35 for what I have..
