Super,
Here's a couple of quick steps and some electrical info. LED's can be considered to have 2 volt drops when forward biased and current in series circuits remains the same throughout. So you do not have 60 ma total. If they are high brightness LED you might have 30ma but 20ma is more the standard. So for calculations....
12v - 2(2v) = 8 volts (resistor drop)
so
R = 8/.030 = 266 ohms.
R = 8/.020 = 400 Ohms.
Standard values are 270 and 390 respectively.
