Mine arrived yesterday and I spent some time figuring them out/installing and documented what I found... they come with no instructions. I bought the smoke version as shown in the OP. They're not very dark at all, but a lot less shiny/silver than the corner lights that come with them. I just kept my original corner lights because I thought they matched better. If you do replace the corner lights, there is no wiring required. The original bulb holders fit right in place (better than the replacements IMO).
BTW, make sure to get the LHD versions, not the RHD versions linked to in the OP!
First off, they are way brighter than the originals, and a lot "whiter." The headlight lenses are actually glass as advertised.... kind of surprising given the price and the trend to poly lenses these days. Here are some pics of the install after doing only the driver's side for comparison (I didn't get around to aiming them yet).
The LED ring light I connected to the lower marker light.

High Beams
I cut the plug off of the old headlight and used it to replace the new one (solder and heat shrink). These are the color matches I found.
I bundled all the excess wire and secured it to the mounting bracket behind the headlight.
To connect the LED ring to the lower marker light I pulled the two spade terminals from the plug, soldered the red and black wires to them, and reinserted. I left the white wire disconnected as I couldn't figure out what it was for; maybe daylight running light switching which I don't have?
(if anyone does know what it's for please let me know!)
Plug everything back in, reinstall the lights, and repeat on the other side. Don't forget to move the two plastic square nuts from the old headlight over to the new ones before installing (the ones that clip into the square holes and are for securing the trim).
TBH, I kind of prefer the look of the original 4 light headlights; but the dimness and poor RHD pattern was something I just didn't want to live with any longer than necessary.
