That's why together with your lack of experience I suggest you buy a commercial replacement bulb with LED's Hi,

They are much cheaper and it will save you the work. Hi, yes it’s possible, but now you can find off the shelf replacement bulbs with LED’s. They are much cheaper and it will save you the work.

In my given application, being powered from car's 12 V battery it's a DC voltage. I used resistors on every LED, I'm not sure what you're not understanding.

Actually I want to make 12 to 16 led 4x3 or 4x4 array but as shown to your experiment it is in parallel and each led has a resistor but in the site you have given it is a series parallel... The led there is in series and every 4 led has only one resistor how could it be?can you explain it to me ...Please help me to conduct my experiment...thanks...
