Extra long life battery — for worry free commuting and all-night rides.

Above: the All Nighter DLG Battery shown beneath a standard DLG battery.

If
you find that you are running out of power too early on your dual or
single Down Low Glow system, there is a new option: the All Nighter DLG
Battery.

It’s twice as long, twice as heavy ~22oz, and offers run
times of 7 hours superbright light for a dual tube system and 14 hours
for a single tube system.  This makes for a worry free week of
commuting or a great fit for nighttime festivals, social rides, and
charity rides.
