What you describe should work, but your current values may be incorrect depending on what point in the circuit they are describing.

Also, you should probably use the lightbulb schematic symbol rather than a resistor, assuming that is what you are still talking about. Resistor would have a resistance value, not a voltage value.

Circuit is OK but the current values is way wrong if all R is same resistance

By the way what are the resistance values

Lightfire,
What program are you using to generate your schematic?

If it is Circuitmaker Student, you will find "Lamp" in Devices -> Displays -> ...

My new schematic I made.

The last bulb ampere ratings is 0.4166667. I forgot to add 7.

Okay.

So total all those four lamps are consuming 1.6666668 amperes. So if my battery is 12 AH rated, I can run the four lamps 3.5999997 (almost 4 hours) SAFELY. Isn't it?

Correct me if I were wrong......................

Thank you!

You ought to be OK with a 3.5 hour run-time with 4 lights when the battery is pretty new.

Once the battery starts getting older, you won't be able to run them as long. You should turn them off when the battery voltage gets down to 12v.
