I do not know how this item is called in the English version of the game, but in the Spanish version is called something like "headlights kit for stage". (juego de luces frontales para escenario).

In the recent days I have experienced the following problem: While it is in the personal inventory of my sim, I can not use it, and on the rare occasions when I can do ... the game interrupted the concert and say "apparently an item is missing from your stage" and when I try to resume the recital, in fact, the item is gone. I would appreciate any comments and / or suggestions you have.

ˇGreetings and Thanks!
