Bongo Fury

hi,
can someone tell me what lights up on the front digital heater control.
The middle bit lights up and the three buttons on the left and also the rear button.
the rest dont light up , fan , mode , and ac. are these supposed too? A bit of a pain in the dark !
thanks

Yes they are supposed to. There are 3 or4 very small bulbs. Seen threads on here about people searching for replacements. Personally I used LEDs
There's a fact sheet

I bought the little bulbs in maplins

Thanks everyone
