I have to use DC circuit theory to calculate the, voltage, current and resistance in a vehicle circuit? ...?

For the following lighting circuit each lamp has a resistance of 12 ohms and the battery voltage is 13. 8 Volts
There is a simple circuit of a battery, fuse and 3 lamps which are in a parallel circuit, how would I calculate the current, voltage and resistance?
Thank you for taking your time to answer what seems to me being a very difficult question.

you said the voltage is 13.8, so we have to believe you
the current through any of the three lamps is 13.8/12 amps
the total current is 3(13.8/12) = 13.8/4 amps
the equivalent resistance is then 4 ohms
