If you know the wattage of the bulb you can calculate the current draw by using the following formula...
P = IV
P = Power in Watts
I = Current in Amps
V = Voltage (12V)
If the bulb is say 15W then the formula would be...
P/V = I
15W/12V = 1.25 amps
P = IV
P = Power in Watts
I = Current in Amps
V = Voltage (12V)
If the bulb is say 15W then the formula would be...
P/V = I
15W/12V = 1.25 amps
