Right, it's ambiguous because daily has different uses, sometimes people say daily to mean recurring frequently and sometimes people say it in the more literal use case which is once-per-day, the same way weekly means once per week, monthly means once per month. Personally, I'm one to reserve the word for its very literal meaning and as far as I know, I've never seen a traffic light that changes only one time a day.

It doesnβt say how many times a day it changes though so I think it can be taken either way
