1984 Cutlass tail light - optional light group?

[gdouaire]

On the 1984 Cutlass, rear lights, noticing what seems to be room for an "extra" light bulb.

Any clue what that is? (red arrow, top image) It's located at the bottom of the light casing.

Part of a "light group" option package?

or maybe a leftover of the backup lights for earlier Cutlasses?

Most likely GM used the same mold, they also did this with the 81-88 Tails, since the design in the back is the same.

I saw a post on this site I believe where some guy opened the hole and stuck another bulb in their tandem with the brake lights. Way nicer and brighter setup.

Indeed - that's what I did also.
