King Hauler + 新燈 question

Any problems or features of 新燈 MFC-01 not fully utilized when install it in the King Hauler?
Reason why I asked is because King Hauler came out many years before MFC-01, and seems like MFC-01 is designed for later models such as the Knight Hauler or Scania.

MFC-01 can use on any Tamiya Truck.

一定合用....放心買新燈啦....

Thanks!
I just read the manual, there are 3 sets of lights J15, J16, and J18 from the MFC-01 that can't be used on the King Hauler.
