Should there be periods for a bulleted list?

Answer 1

But each bullet is like a sentence not just a single word

Answer 2

If each bulleted item is a sentence, then yes, a period is needed at the end of each.

If each bulleted item is not a complete sentence, no periods are needed.

Just make sure your bulleted list is all the same -- all sentences or all phrases of the same type or ??
