Re: IML: Push button light source

[PAUL WENTINK <randalpark@xxxxxxx>]

1960 was the final year for the push buttons being lit by a light bulb.

Beginning in 1961 and through 1963, both banks of buttons are lit by 
the large electroluminescent panel mounted along side of the buttons. 
It is within the cavity in the dash containing the buttons. The clear 
button "arms" transmit the light to the letters, as it does in the 
earlier models where the light bulb is used.

This method was used in addition to the felt padding to eliminate the 
chance of a distracting outline of light showing around the buttons 
that would brighter than the lighting through the faces.

The light source is a lightbulb behind the buttons and
it is not attached. The clear lucite in the buttons
is transmissive, sorta like fiber optic cable (but
not) where shining a light on one side allows the
light to pass through and be visible on the other
side.
