All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Lighting the lamp or the torch you mentioned doesn't make you a disbeliever, even if some people associate it with disbelief doctrines, as long as you didn't believe in anything related to that doctrine, but rather did it as a way of following traditions.
We think your question is due to whispers which we have already advised you to ignore and not to give in to them. We made this clear to you in the answer to your previous question No. 2626653. We reiterate our advice to you to repel and ignore those whispers, especially in issues related to disbelief.
Allah Knows best.
