@haseeb92
you dont need to worry about the resistor, simply ask the person you buy it from to give you resistors which can work with a 14V battery.
the LEDs are bought with the resistors.
Ohms law V=I x R
V=voltage
I=current
R=resistance
you can use this equation to find the resistance you require, because different color LEDs have different voltage requirements and therefore different resistors.

thank you sir, agreed it takes a lot of time, and is a very tedious process. took me 3 days to make them, and i still have to hook them up with the car properly.
@ateekt
thanks man
@N2O
thank you for your appreciation.

i dont get what you mean to say.
