Alert me when someone posts in this thread:

You could measure voltage on each of the lamp wires. Presumably the ground lead is the black wires hidden behind the black hose? If you don't get good voltage at the wires, then a new lamp housing isn't going to help.

First unplug all the wires & protect them from touching anything. Then for each bulb socket, use your meter to measure voltage from that wire to ground, while someone sits inside to press the brake pedal or use the turnsignals or whatever, to energize each lamp.

I can imagine that a bad ground connection would be a common failure in a fiberglas car. Measure how good the continuity is from that black ground wire back to the negative battery post. Do you get rodents chewing on wires out there?

You need some local electrical geek friend who enjoys taking appliances apart... AND putting them back together. (This would be fun if I wasn't 2500 miles away...)
