1991 seabird sea core 173 wiring

[pumfe]

My bow navigation lights worked last year and when i was getting it ready for this season, i noticed the lights arent working. i did a continuity test and there is no continuity. i would like to re-run wires, but the hull is filled with foam and there is no access hatches. i tried tugging on the wires with pliers from bow side, and they did not budge. i can pull from the console and there is some play, but the wires that connect to the light assymbly dont move at all. anyone have any ideas other than running wires that would be exposed and visible to all on the boat?
thanks

Can you get access under the gunnel, or do you have a rigging tube running from helm to stern under the deck?

hi, thanks for the reply. i actually meant bow lights. there is no access at all. when i un-screw the light assymbly, there is about a 2 inch round hole that goes down into the foam about 4 inches or so.
