I'll have to admit I would'nt know the difference between incandescent and LED.  However
everyone (including my Bentley - copyright 1991) refers to these indicater bulbs as LED's.

After reading the responses that corrected my error I went back to the Bentley to have a
look again.  In the picture displayed they show what I assume is a real LED (page 90.19) and
a point is made of the polarity of the bulb.   I did not notice this on the bulb that I used
in my own repair.   The bulb I used only had two thin wires that were exactly alike.   It
would appear that what I installed was in fact an incandescent.
