Heater Control Light Missing

similar rear frame used for airtemp control. they had a light that bolted on in a holder, powerd off the dash lights or column shifter quadrant feed it hada press fit blue cap and illuminated the buttons which where metal cased clear plastic with etched words. the light shone on the plastic and was reflected by foil coated card forward down the plastic strips to the front of the button. like very poor optical fibre or light guide

not very good
