Step 1: buy 40 LEDs. I recommend

- good folks, low prices. Step 2: wire them up.

You need to know what voltage you will power them with, and the forward voltage drop (usually listed in specifications for a specific LED).

How about *making* the numbers with 3" high 5x7 dot matrix led units.
Just work out which LEDs to light and calculate appropriate resistors to run it from the bell transformer.
Dont forget to mount the numbers in the shade under the porch - or black paint over the unuserd LEDs to make the numbers visible in daylight.
