The numbers have long since disappeared  but if I remember correctly I just
went down to Auto-zone and grabbed some small, medium & large bulbs:

Small : Running light, 3/8" diam., 4.5 Ohms, 256 mA

Medium: Interior Illum., 19/32" diam., 1 Ohm, 1 A

Large : Exterior Signal, 31/32" diam., 1 Ohm, 2.6 A
         (Use *both* elements in parallel)

(Note: DC Resistance values are from *cold* bulbs)

Be well,
