candle
An object made of wax with a string running from top to bottom which is set alight. Its most common shape is cylindrical.
Has seen more use in the past, but it is still used as a light source in some places, in religious ceremonies and as a symbol of different things such as hope.
If the candles are worn strapped to the head with a headband, there might be a reference to the youkai Hashihime, or the curse ritual Ushi no Koku Mairi (which also involves a mallet or hammer, a straw doll and nails).
