WARNING!!!

•  Make sure the illumination angle will not dazzle oncoming traffic, 

and never position the visor to the bottom of the headlight.

•  Before your trip, please make sure the light is firmly mounted 

to the bracket and it lights up.

•  Always attention to the remaining battery power by checking 

the indicator periodically while using.  

CAUTION!

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

you carry a spare cartridge battery and light.

•  Do not attach the cartridge battery if water droplets, dust, or 

other foreign matter is attached to the unit. Also, do not touch 

the terminals.

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 temperatures will 

cause the rechargeable battery to deteriorate faster. Do not 

place the light inside a vehicle or near a heater.

•  If the illumination time is significantly reduced even after 

proper charging, the rechargeable battery may be nearing the 

end of its service life. Dispose of the battery as described in 

“Cautions for dispose”.

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.

Cautions for dispose

Dispose of used cartridge batteries appropriately according to 

local regulations.

Before using the light, read this manual thoroughly 

and keep it for future reference.
