Such fighters might have
been hit, resulting in flashes and perhaps flames or trailing smoke
to be observed by the gunner,'

I seem to recall that the fuel injection in the Daimler-Benz engine
resulted in a puff of smoke when the 109 pilot pushed over, which
caused a lot of "confirmed kills" in the BOB, and no doubt elsewhere.
