That's true but it does not harm the operation of the motor. One or two of the bulbs burnt out would still result in an open circuit only for the light bulbs assembly since they are electrically connected in parallel as a unit.
My suggestion of placing two identical wattage 120V bulbs in series supplied by the two 120V legs (240V equivalent) acts like a load doubler when a more appropriate single 240 V bulb load is not at his present disposal.
Of course he could as well just use a single 240V light bulb to be powered from the 2 120V legs but when it blows out the result would the same nevertheless. It would have to be parallel with the motor circuit and it would light up at the same time the motor is running and it would likewise be off if the motor is not running.

I wouldn't put anything in series unless it has to be in series - if one blows, the other goes out, too.

You need to have a sensor and/or a relay that would activate the indicator light bulb when your pump is running.
It's also possible to employ two 120V-bulbs of the same wattage in series and electrically connected in PARALLEL to the 120V legs.
