The socket that connects to the bulb is readily available for around rm16~20 each if not mistakenly, but you can't find the other female socket that connect to the chasis. Those female sockets are not available, same as those used on the sidemarker, citylights. You can't find them.
The option is buy the male sockets, then just have the wire welded on the male sockets then secure it with silicon. Not OEM set up but it's working anyway. PM if you want the male socket.
