I can only guess that your measurements are with no bulb in that circuit and if that's the case then that's why your measuring the full 40 volts that the power supply has.

With no bulb in the circuit there is no current draw thru the resistors bolted down on the floor of the chassis that drop the 40 volts down to 28.

The short of it is no bulb, no current draw and there for no voltage drop.
