Running the mod with all DLC enabled, I noticed that:

Bionic Duplicants are not included in the light emitted by default by a duplicant. It would be nice to have a Bionic Duplicant work the same as a duplicant on this. Or even better, to have the possibility to set a different light for bionic and for classic duplicants.

The same applies for the configs under the minionLightingConfig in the config.json. A Bionic Duplicant with a minor hat won't have any light emitted by its hat.
