Re: Relay?

That makes sense, it is very similar in appearance to Echlin's 6-volt HR200 aftermarket headlight relay as pictured in their April 1965 catalog.

What raises my curiousity is that headlights were normally protected by a thermal overload switch (self-reseting circuit breaker) to allow some lighting even with a short. In the case of this relay a 30-amp fuse is much too large for protecting the relay winding so it must be there to protect the load, but for headlights a thermal breaker would have been superior. Packard used thermal breakers on headlights way back, my 34 has that feature and I doubt it was innovative at that time.
