Showing available 1/21/2019... I would assume that means ready to ship around that date. Comes out to $1,035 with UPS standard shipping to Los Angeles.
They also have the install instructions available for download, pictures only (think ikea) but it looks like any other headlight install. I like everything about them except the wire going to the battery. I assume the amp draw of the LEDs exceeds what the factory harness can provide but I'm not keen on adding any un-fused wiring under the hood.
A fuse is easy enough to add if amp draw specs are available. But then they don't fit my (possibly narrow) definition of plug and play. I have run wiring into the fuse box (for my sub install) to keep everything looking factory but I'm not sure the effort to run wires to both front corners is worth it.
I think the single angle straight-line DRLs on the Osrams look better than the MK7.5 style but not sure if that's worth almost double the price. I'm leaning back towards the Mk7.5 lights. Fully plug and play (as I understand it), but sold out too, haha.
