Apparently this is Toyota Factory Installed and Not a Mod

Has anyone seen this before?

OK Chatgpt was wrong - these are a mod (gemini.google.com)

Those red bars are a user modification, not a Toyota factory-installed part.

On a factory 5th Generation 4Runner (2010–2024), those two vertical sections on either side of the rear window are simply matte black plastic trim pieces. Owners often find that area a bit "empty," leading to this very popular aftermarket upgrade.

What are they?
Commonly called "LED Rear Pillar Lights" or "Tail Light Extensions," these are designed to replace the stock black trim. Depending on the version the owner bought, they usually function in one of two ways:

Static Reflectors: Simple red plastic pieces that reflect light but don't actually turn on.

Functional LEDs: The more common version, which is wired into the existing taillight harness to act as additional running lights, brake lights, or even sequential turn signals.

Why do people add them?
Aesthetics: They extend the "look" of the taillights upward, giving the rear end a more modern, "Volvo-esque" or Cadillac-style vertical lighting profile.

Visibility: They provide more light at eye level for drivers following behind, which can be a safety benefit.
