I got OEM foglights installed into my car and they were working fine then after getting my car inspected one time they stopped working, the interior switch light wouldn't come on either. Someone told me that it might be the relay which is a 12v/40amp 4-pin which i couldn't find but i read that a 12v/30amp could work. I install the new relay now the interior switch light will come on but the relay is making a buzzing sound and the actual lights still won't come on. Any suggestions would be greatly appreciated.

Thanks in advance
