The most well-known custom of is the lighting of bonfires throughout Israel and worldwide wherever religious Jews can be found. In Meron, the burial place of Rabbi Shimon bar Yochai and his son, Rabbi Eleazar, hundreds of thousands of Jews gather throughout the night and day to celebrate with bonfires, torches, song and feasting. This was a specific request by Rabbi Shimon bar Yochai of his students. Some say that as bar Yochai gave spiritual light to the world with the revelation of the Zohar, bonfires are lit to symbolize the impact of his teachings. As his passing left such a "light" behind, many candles and/or bonfires are lit.
