That's nice to know. After reading this I went out to the shop and looked, none of mine have the switch to change over. Guess I may have to break down and spend some money to bring myself back up to date.
An old trick was to remove the plastic face plate and install the little LEDs from the bottom of the floor board and have lights showing through down by the pilots feet or on the dash itself so you could look inside the canopy and see the lights. Nothing special, just looked cool.
