Before using the light, read this 

manual thoroughly and keep it for 

future reference.

Manual

 WARNING!!!

• This light emits an extremely powerful beam equiva-

lent to automobile headlight so it may cause a hazard-
ous situation depending on the beam angle used. 
Be sure to direct the light beam downward so the 
driver approaching does not get dazzled.

• Before your trip, please make sure the light is fi rmly 

mounted to the bracket, it lights up, and the light is 
not blocked by baggage, etc.

• Always attention to the remaining battery power by 

checking the indicator periodically while using.

 CAUTION!

• Do not stare at the light when it is illuminating.

Otherwise it may damage your eyesight.

• Do not place it within children’s reach.
• In preparation for unexpected battery shutoff, we rec-

ommend you carry a spare cartridge battery and light.

• Mounting the light unit too close to a wireless comput-

er may adversely affect the reading of the computer.

• This product is water-resistant under normal daily use 

and can be used in the rain. However, do not inten-
tionally submerge it in water.

• If the light unit or parts become dirty with mud, etc., 

clean with a soft cloth which is moistened with mild 
soap. Never apply paint thinner, benzine or alcohol;

Cautions on recharging

• Avoid charging in direct sunlight or in a vehicle 

parked under direct sunlight, and make sure to 
charge only when the ambient temperature is 
between 41°F and 104 °F (5 and 40°C).

• Before charging, be sure that no dust or other 

foreign objects attach to the USB plug.

• Do not subject the light to vibrations while charging.
• Once charging is complete, be sure to disconnect 

the USB plug.

Cautions in use

• Charging, discharging, and storing in high tem-

peratures will cause the rechargeable battery to 
deteriorate faster. Do not place the light inside a 
vehicle or near a heater.

• When the operating time decreases signifi cantly, 

the battery life is close to an end. Replace the 
cartridge battery with a new one.

Cautions on storage

• Cool and dry storage is recommended. For long 

period storage, it is important to charge the battery 
30 minutes every 6 months.

• When you store the cartridge battery alone, be sure 

to install the cap.
Otherwise, damage or a fi re may be caused by 
short circuit.

Cautions for dispose

Dispose of used cartridge batteries appropriately 

according to local regulations.
