HELP need to fix side markers on 88 honda civic

I just bought an 88 civic and to pass safety the side marker lights need to work. I already changed the bulbs that didn’t fix it, I checked the fuse box and could not find a blown fuse, does anyone know what this could be?

Its got to be wiring, if you have a test light then you can test the wires going to the lights.

I replaced some marker lights in an 88 Honda long ago. They were just corroded beyond fixing given the replacement cost from Certifit. I don’t know if they still sell them though.
