My Yaesu FT-4700RH had 4 "grain of wheat" style lamps
to provide panel/display backlighting. 3 of them had burned
out. These lamps are accessible from the back of the removable
control head. They are covered with pliable orange plastic covers
and inserted through holes in the PCB from the back side, with the
two leads bent over and soldered to pads on the back side of
the PCB, so they are easy to remove. (Save the orange plastic
covers to use on the replacement bulbs.)

I would suggest replacing them with LED's instead, then it is a one time
fix..
