Hi i have an AC powered LED bulb which i want to run with a 12VDC car battery. Can anyone provide me with a circuit to implement this or tell me what modifications to do?

Thanks.
 

Your mains LED bulb will have some circuitry in it to convert the mains AC to a low voltage DC which will not work with 12v DC. So either you convert your 12V DC to mains AC or break into the bulb and try to bypass this circuitry. It really is not a good place to start from, buy a low voltage LED bulb.
