My wife's Lezyne Deca 1500XXL stopped taking a charge, at all. Taking
it apart, I saw that the batteries were made in July 2015. Not too
good for it to stop working that soon.

Some of my bikes have dynamos that are 30 years old. They just keep
going and going and going...


Until you get to a red traffic light, to a stop sign or into a traffic
jam. The perfect spot at night to get hit by a car driver who didn't see
you because you were on the only unlit vehicle around.

Yes, Joerg, we know: "Danger! Danger!"

First, I've been riding regularly at night since roughly 1977. The event
you describe has never come close to happening to me. At a red light or
stop sign, the motorists behind me are coming to a stop anyway; plus my
bike has reflectors.

Second, if you're really that terrified, it's easy to put a $5 blinkie
powered by AA cells on the back of a bike. That's perfectly adequate for
the fearsom scenario you imagine.

Gawd, you're afraid of traffic! What a wimp.
