MAINTENANCE
Inspect and test your light and bracket apparatus before every ride.
Keep your light clean and free of dirt, be careful when cleaning any mud or dirt from the lens to
avoid scratching.
Never use a high pressure spray or hose on your light.
Do not use harsh abrasive or corrosive materials to clean your light.
For extended periods when your light is not in use fully recharge the light once a month, as a long
duration with no charge is detrimental to the cells.

look directly into the light or shine directly at others, including other road users.
Do not charge the light in an enclosed place, or with the lens in contact with potentially
combustible material.

damages arising from the use of their product in any circumstances.

CHARGING
Fully Charge your light before first use.
Locate the charging port by pulling away the silicone Storm Cap.
Fully insert either the Smart Charger or USB top up cable and begin charging from a mains or USB
supply respectively.
If you are using the Smart Charger the LED on the charger will go red for the first 95% and then go
green for the trickle charge.
On the rear of the light the charge LED(s) will flash green to indicate charging and then turn solid
green when the light is 95% charged, then the remaining 5% is trickle charged.
NOTE: Sirius will require the 1.5A Smart Charger (EXPCHARGERSALES) from
www.exposurelights.com, to initiate trickle charge.
If using the Smart Charger, the charge status is indicated by the LED on the body of the charger
(red = charging, green = 95 - 100% charged). The LED(s) on the back of the light may continue to
flash, even when fully charged.

LIGHT OPERATION & BATTERY LIFE
'how to' videos
Located on the back of the light is the stainless steel Function Button and a single LED. The LED
indicates both mode and battery life remaining.
To turn the light on press the function button twice in quick succession, the light will then turn on in
the brightest mode.
To switch between high, medium and low modes press the function button once, repeat this
process to cycle through the modes.
The LED on the back of the light will initially indicate the mode the light is in:
Green – High.
Amber – Medium.
Red – Low.
After three seconds the LED on the back of the light
will indicate battery life remaining. See Fuel Gauge table (right).
To check battery life status with the light off, press the function button once. LED feedback will
display current status, i.e. Green for 100 – 80%To turn the light off hold the function button down
until the light emits two flashes and then release.
NOTE: If you are using an Exposure Support Cell with the light then the LED will pulse green to
indicate the light is charging.
LOW VOLTAGE FLASH (ZENITH, DIABLO, AXIS & JOYSTICK)
To warn the user when the light has 10% or less of battery life left the light will flash. It is then
advisable, if it is safe to do so, to put the light in a lower setting to prolong battery life. See the OMS
section for more detail.
NOTE: The light will continue to give off these warning flashes, regardless of setting, until its
battery is charged back above 10%.
FLASH MODE
To activate the Flash Mode first the light needs to be ON. Hold the Function button down and
immediately release after the light emits a flash. The Flash mode can be activated from any of the
CHARGE PORT
constant brightness settings.
To return to the constant mode press the Function Button once. NB: The light will then return to the
brightest setting.
In Program 7 the Flash Mode is replaced with the Morse Code for SOS. For more information about
changing programs see the OMS section of this guide.
DAYBRIGHT (SIRIUS ONLY)
We recommend using your Sirius in DayBright mode during daylight hours for your safety.
To activate DayBright your Sirius will need to be in Program 1 (see OMS section) and then activate
Flash Mode (see above).
