what are these extra resistors/fuses to the right of my 5e3?

is this because the solder lugs are exposed on that style pilot light? or is there something else wrong with them?

I think its if you slap too much solder on, or you manage to get the lugs accidentally touching something, or you bend the mounting bracket to get it to fit into a BF chassis and then cause a short from the lamp side to the mounting screw. But I've never had any trouble with them (touch wood )

I was refering to the cup shaped part that holds the bulb being shorted to the chrome bushing (ground) if you drop the bulb while removing or inserting it with the power on. Not a problem with the modern black plastic holder.
