By Hyunsu Yim, Nicoco Chan, Minwoo Park SEOUL (Reuters) -While South Korean protesters have long employed songs, dances and chants, customised light sticks popular with K-pop fans have emerged as an effective new tool for demonstrators calling for the impeachment of President Yoon Suk Yeol.

South Korean President Yoon Suk Yeol survived impeachment on Saturday as all but three members of his People Power Party boycotted the vote, granting the embattled president a temporary reprieve.

Opposition lawmakers failed to impeach President Yoon Suk Yeol over the political crisis he sparked by declaring martial law earlier this week. Tens of thousands of protesters had gathered.
