Abstract: A bulb socket mounting structure inhibits a bulb socket mounted on a panel from being turned to prevent the bulb socket from unintentionally coming off the panel. The bulb socket mounting structure includes a bulb socket with a fixing flange and a locking piece extending from the fixing flange. The locking piece includes a bending portion extended tangentially off an outer cylindrical surface of the fixing flange with a hook at the end of the bending portion away from the fixing flange.
