Hello and welcome to the forum! OK, MY guess is a set of under car running lights.
Lets all keep this going until a tracing of the wiring is finished. Oh, some help, IF you do trace it, the wiring diagram in the service manual (Free download here in the forum) can help with the color code of the wiring IF it is spliced into the harness (it may not be connected). There, anyone else? LOL
