I haven’t seen flickering (flashing) marker lamps like that since the kerosene went bad and the flame flickered up and down.

Although I run vintage equipment, my railroad operates in the present, thus the marker lights have been converted to electricity. Railroad management wanted the option to flash them in various patterns to increase visibility.
I have since decided that I have no need to individually control the markers, so that will free up one button for an additional sound effect. I’m also thinking of experimenting with the firebox flicker effect for the interior lamps.
