You take standard 5mm LEDs, cut one lead real short and 
solder a 1/4W or
1/10W resistor to that lead.  If your console has sockets 
for the lamps,
this combo can be plugged into the socket after the leads 
are trimmed to
the right length.  if no sockets, then they can be soldered 
into the PC
board.  The resistor value needs to be figured out by trial 
and error,
due to the variations in LED efficiency.  if the console has 
heep-alive
resistors that keep the filaments slightly warm, these will 
need to be
removed, as they will keep the LEDs partly lit.
