Castiel

Hi guys I bought 2003 camry altise v6 so the the left quarter panel signal blinker isn't working even when I swapped over the working one from the right the left low beam head light isn't working either I tried to undo the bulb from watching a YouTube video buy it won't turn its stuck any suggestions on what I should do now that be great but I dont know anything about cars so obvious I should take it to a mechanic im just wondering if anyone had this issue ?
