Yes I agree with you on never to depend on one light. Guess what I meant was that if you are to get 2+ lights, make at least one of them a very good bright one. IOW it would be absurd to be equipped with 5 weak lights none of which is visible from distance.

Re return policy, it's only practical within the country. For most of them you would have to send it back to China, Hong Kong, etc., not worth the shipping cost unless the item is >$100, plus the waiting time. (I'm still waiting for one of my orders, Hopefully it will arrive before I forget it and orders something else )
