After seeing another "best light for "x" dollars" posting - I have decided that at some point we could discuss what cyclists think of when talking about "all the lights" they need to be safe when out and about in any conditions.

I've posted "ultimate system" threads before - but this thread - I would just like to know what forum members think the "minimum light setup" for fool proof night riding should be.

It seems to me that no matter what devices you use - you need two for front lighting and two for tail lighting. And fine point to this "minimum" is four individual battery sources as well.

I know many would not agree, but just for kicks, shouldn't a good light system have a bar mounted as well as helmet mounted light? And shouldn't they use separate batteries?

And shouldn't you always have a "backup tail light", with a "backup" battery as well?

So if you happen to think this way, what kind of dollars are we talking for a "bike light" - now......?

You brilliant comments are requested.
