307 oil warning lamp is off

At the end of general maintenance (oil-oil filter-spark plug replacement, etc.) in my 2004 XT 307 gasoline car, we noticed that the oil fault lamp never lights up at the first contact or when it is working, is it normal (only the fault is on), or it should be flashing at the first opening (if so) thank you for your help in advance)

There is no problem.No oil lamp lights on either the first contact or the first start.

Normally it was not yam but if I did not check that my son did not burn, it would be greasy.
