-
Press and hold the on/off button for around 1 second to turn off and on.
OVERHEAT PROTECTION
The overheat protection circuitry in your light ensures that it operates at
safe temperatures to ensure a long life. The continued heat build-up is the
biggest enemy of LEDs and causes lower lumen output and lifespan when operated
too hot. Under proper operating conditions, your LED should last 50,000+
hours. (See battery info for battery lifespan)
When your light is on many factors can cause it to get too hot (inadequate
airflow, mud, dirt, walking up that hill).
When this happens the circuitry in this device will automatically go into “Medium” mode. Once the airflow over the light has improved and the running temperature is reduced the circuitry will kick the light back into the previous model.
HOW TO MOUNT THE HEADLIGHT
UNIVERSAL BRACKET INSTRUCTIONS:
Open bracket by pulling the thumb lever down, then un-clip the thumb lever
from the cam hook to open. Adjust the rubber strap length to fit the bar by
moving the strap up or down the rungs located under the swivel light mount.
Once the length of the strap is adjusted for best fit, install around
handlebar or seat post by inserting thumb lever into cam hook, then rotate
thumb lever upwards towards swivel mount to lock. If the light still moves on
the bar open the thumb lever and shorten the strap by moving the rubber strap
up to the next rung.
HOW TO CHARGE BATTERY
WARNING: Batteries can only be charged using a USB adapter with a 5v output or USB port on a computer. Only charge batteries in a dry environment. Light has smart charging technology which ensures longer battery life and will not overcharge. Charge times depend on the light model being charged due to internal components inside the light. When the indicator turns flashing red, it means the battery is below 20%.
