Did you inspect the female terminals' tension at the dimmer switch
harness? Are they corroded or clean? Other than that, you most
likely have high resistance somewhere common to both bulbs. This
could be a poor ground, splice, fuse holder, etc. in the system.
I don't know what kind of fuse protection is used on your Fairlane,
but *if* it uses a circuit breaker, the breaker could be faulty, or
the contacts between the fuse box and breaker could be loose which
would heat up the breaker and trip it thermally.
