They are just fiber optic cables that allow you to see if a brake light is burned out. The fiber optic uses the brake lights for illumination, so if a bulb is burned out, the fiber doesn't light up.

This indicator is part of the 'Fiber Optic Lamp Monitor' option. On the Park Avenue, it may have been standard equipment. Two fiber optic cables with polished ends 'transmit' the light in each rear lamp housing. The other ends terminate into red lens in that little housing at the rear of the roof.

You might also have the indicators on the front of each fender towards the front top edge of the fender. They are used for front turn signals and high beams head light.
