Last out of the headband, the pair of "back up" lights.

These are the two LED assemblies that allow the position tracking system to keep an eye on you when you're looking over your shoulder, keeping the in-world feel alive.

The assemblies are also conveniently labeled right and left. Labels make a fixer's heart glad.

With a bit less space to spare in the headband than in the visor section, these LEDs light the edge of a light guide before passing through the diffuser.
