I can confirm that DISP switch, left and right side circuit breakers (amps labels) and GND PWR control panel do not have backlighting in C-model. Same with the right side circuit breaker panel FCS BIT ON/OFF -text. This is a thin aluminium sticker in real life. There are backlit panels with texts FCS CHAN 1, FCS CHAN 2 etc on the L and R CB panels but the actual circuit breakers with number labels are not backlit.
EDIT:
Also the throttle cover plate MAX, MIL, IDLE and FRICTION are not backlit.
