> $7000 DRM tail light units

What car has that? Please do not spread misinformation.

The Lightning taillights are expensive, a couple grand directly from Ford, primarily because of the integrated blind spot radar. That is the part that needs to be re-paired to the truck if you replace it, the taillights themselves are same as they ever were. Most of the time when someone breaks a taillight they just grab one from eBay and swap over the BLIS because it wasn't damaged.

Also, expensive taillights and headlights are 1) not unique to the Lightning, and 2) not unique to Ford.
