Some photos.

First of all, I put a 1K resistor in series with a 68 ohm resistor under the chassis to use as a voltage dropping resistor for the LED.

Heat shrink tubing was placed over both resistors and both solder joints, and the free end was then soldered to the terminal strip where the white wire for the Stereo Beacon lamp formerly connected.

I used some hot glue to hold the new LED inside the old plastic shell of the incandescent bi-pin lamp.

After some careful soldering and more heat shrink, I now had an LED Stereo Beacon. Unfortunately, it is running dim, as you can see here...

...and here...

...and here. Notice the tuning meter is illuminated very well indeed.

Made by Pinball Life, this LED, connected to a miniature bayonet base, can be positioned where needed for best light.

This design allows the LED itself to be placed close to the back of the meter, allowing much greater illumination than was possible with the 47 lamp.
