OK, I removed the resistor board and fed the lighting board via two 510 ohm resistors (one in positive and one in negative so effectively in series).
Ran the car on 10 volts for over 30 mins and no problems.
Not saying this will work with Go! Plus but worth trying if you want the headlights working. The tail lights do not have transparent lenses so did not bother fitting tail-lights.

The white thing is a piece of lead that I had fitted for running in an event.
