What is the light bulb number for A/c Controller

[apanello]

2003 Ford Explorer Flex XLT

The 1,2,3,4, fan speed control nob has a backlight.

It does not light up unless I punch it. I do not like having to punch it every time I start my Ex.

Anyone know the bulb #?

Bulb is not listed at Autozone or O'Reily's. Some members said they went to dealer and scored a couple but never posted a part number. I took my OEM bulbs which does not have numbers and matched it up with what was available at parts store. These are really tiny bulbs. I used Sylvania 2721. The wattage is 1.2W. I putted them in my vehicle and compared the brightness to the rest of the dash and it looks good to me. There was also 2723 but that is 2.3 Watts which I did not open to try in the controls figuring it may be too bright and returned unopened. Hope this helps others, I looked on forum and came up empty handed.
