Maqueen PLUS V2.1 2 large red LEDs software control ?

I have purchased 15 Macqueen PLUS V2.1 robot cars to use as a teaching aid for 12-13 year olds in a school. I have been starting to play with it , but noticed early on that the extension library that I was using did not allow for control of the 2 large LEDs(headlights?) at the front? I have spent hours and hours trying different browsers, extensions, etc etc to no avail. So can anyone please advise me on this . Are these 2 large Red LEDs at the front actually software controlled and if so , what is the correct extension I should be installing (I tried about 3 different ones with no luck ) . appreciate any help on this Dave
