Not the relay-and-resistor type, but you could often find surgistors
(ceramic disc-capacitor looking things, but I believe, made of
carbon) soldered in the filament string as part of some old sets.
Then there were the "bulb savers"--small discs probably containing
nothing more than a carbon resistor that were placed in the bottom of
an Edison-base lamp socket between the bottom contact of the socket
and the end contact of the bulb. I wonder if these were ever
encountered in the UK--it would seem that one would interfere with
the bayonet-style lamp sockets used there.
