Hello, I just ordered the cool white version of the Thrunite TN4A. I have 2 simple questions. The Thrunite TN4A comes with an o-ring. Do I have to install the o-ring for the light to be waterproof, or is it just a spare and it is waterproof right out of the box? I really don't want to have to instal the o-ring just to b able to go out in the heavy rain. Also, what kind of batteries are best for the TN4A? Thanks in advance!
