bulbs for ventilation controls. Options

[Olympic 914]

Going to be ordering some LEDs for the dash and need to know how many bulbs are used behind the ventilation controls. I see a bulb chart from Jeff that shows 4 bulbs are used there. Type 2721

I will be ordering Blue for the cold air and Red for the warm but are there other bulbs just to backlight the control? Guess I would order White for those.

and can you access the holders without removing the control unit from the dash?

I haven't climbed under the dash yet to check.

I believe this is the same unit as in my ‘72 build date May 72, l seem to remember that the lower holders are there but they do not open to the faceplate. The arrows are luminescent not translucent. For the upper holders, if I remember correctly the left side is clear and the right side blue but I don’t remember how they indicated operation?
