Is there a low battery alert?
Of course, When light off, short press on/off button, red LED light will
show current power, totally 5 grade. It is very convenient to control power,
efficiently avoid turn off. When power is lower than operating voltage, red
LED will blink 3 times then off. Light couldn't on when in off condition

Can I use it in rainy day?
This bike light is IPX4 waterproof, if you ride in a heavy rain I would
strongly suggest you to add some sealant to prevent water from going in.

How long about charging time?
Rear light charging time: charging take 3.5 hours. When charging 3 red
light flashing. Full charge red light constant on

Does the power keep for a long time?
When under the normal brightness, the rear light endurance can last for
7hours. About the full battery standby, when the rear light button is on
but light is off, it will last for 14 days, and the light off standby over 3
years. You do not have to worry about the power problem absolutely

Warm Tips:
1.Please charge this light if six months no use, otherwise may cause
battery less charged.
2.IPX4 waterproof. Could be used in small to moderate rain, please don't
suck the product in to water.
