Recently purchased a set for my 2017 4Runner. One of the marker lights was half-dead on arrival and I broke another during install, so I contacted Car Trim Home and they sent me an entirely new set (4 LEDs with a wiring harness). I've installed the remaining two, so I have two LEDs and the wiring harness leftover.
Note that you will need an ATC add-a-fuse and extra fuses for install. Add $5 ($20 total) and I'll throw in a set.

Local pickup only - not worth the cash for me to drive far.
