    The concept of how trailer lights (DC) work is really simple once you understand it. First, check every ground connection at every light.
    Then, get a test light, and start and the vehicle plug and then just after the trailer plug and keeping working back until you find the issue. And when in doubt, if the trailer is old, pull all the old wiring and start with new, often saves tons of time vs chasing gremlins on old cracked wiring on a rusty trailer.

    Nope. But you will have corrosion where contacted with non galvanized metals and in time that will mess with lights just as bad.

    dblkluk is right. Dis-similar metals will corrode. The hardware may not be galvanized. Could be s/s, which is BETTER, but same troubles apply.
