:)If The original lamps are those pea sized incandescent lamps, make up 3 or 5mm led superbright diffused lamps (put series resistor to led and shrink sleeve).(3 or 5 depending what size led will fit into recess.)
Observe polarity and install. I recently did IC-765 meter lamp with 5mm super bright, and dulled the lens with a scotch pad.
Looked really spiffy.
