George!
I don't know to who is the question, but thinking it was for me here is the answer.
if you have 1.5 volts bulb 15mA X 2
the total will be 3.0 volts 30 ma.
so, feeding them with 12volts you need to subtract 3 volts and the total in this case 9, you divide by 0.03 total 300 ohms resistor.
is you have different resistor you need to put them on series to reach 300 ohms.
I install them on a pole like a pole fuses.
