Battery status feature
The status LED tells the percent of battery
charge that remains.
Status LED color
Charge remaining

additional hour.
A bicycle without correct lights and reflectors
might be difficult for other people to see, and
you might not be able to see. If you cannot see,
or other people cannot see you, you could have
an accident. Make sure your lights operate
correctly and that batteries are charged.
WARNING
To change mode

Traveling with the light(s)
The light contains a lithium-ion battery. Certain
restrictions may apply to this product when
traveling, especially when traveling by air. Always
check with your carrier for specific restrictions
prior to traveling with this product.
Caring for the battery
Store the light at room temperature in a dry
place. Avoid moisture, or extreme hot or cold.
Store the light in the charged condition. Avoid
“deep discharge.” Battery life will decrease if the
light is stored in a fully discharged condition.
Over time, the run time of the battery will
diminish. Expect about 500 full charges,
depending on care. After a full life, the battery
will continue to charge but with a lower run time.
When the run time is unsatisfactory, please
recycle. Do not open the case of the light or
incinerate.
