The light and charger are ready for use when delivered. All you have to do is charge the battery
before using the product. See charger section.
Safety instructions:
Carry a spare light with you at all times, as the product can potentially fail unexpectedly at any time.
Heat generation:
Our Piko is not a ashlight. The housing may heat up; so make sure that you always keep the light at
a safe distance to any combustible or ammable materials. Could cause re or death!
However, quiescent operation (without cooling the light housing via airow or the like) is possible
at any time and will not damage the product.
Important! When the light is being used in a stationary state, the light will be dimmed after a few
minutes to reduce the light's temperature. Continuous operation at 8 watts is only possible with air
owing over the housing!
Water resistance:
All Piko components are waterproof and can of course be used under extremely severe conditions.
However, the Piko light is NOT a diving lamp and is NOT suitable for use under water.
Read this manual before using

Warning! Avoid looking directly into the light emitted by the light or shining the light
into your own eyes or the eyes of another person. If the light accidentally shines into your
eyes, close your eyes and move your head out of the light beam. Do not use any strongly
focusing optical device to look at the light beam.
In cases where the light is used in a public or commercial setting, users should be
provided with training concerning the safety measures for laser light.
General:
No tools are required for mounting this lamp. The
helmet mount is already mounted to the lighthead.
You can attach this helmet light to almost any kind
of helmet with ventilation openings.
Note: The adjustability of the lighthead is
dened by the silicone rings at both sides
of the lighthead. To always ensure awless
functionality, both black screws must be
tightened securely.
Insert one part of the velcro strap into one of the
ventilation openings available on your helmet. Each
helmet is dierent; therefore, we cannot give precise
advice on which opening to use. You may need to try
various positions and nd out which one suits best.
Tip: Many ventilation openings are sloping to the
front. Thus, you should attach the helmet mount
as close to the front rim as possible. Only then the
helmet mount will not slip down. Direct the light into
a straight forward position and tighten the velcro to
avoid slipping of the lighthead during use. A potential
bending of the baseplate is not a problem as the
plastic used is highly exible.
How to mount the lamp on a helmet can also
be watched in a video provided on our website
in the support section!

on the helmet mount/headband. Only one
screw but both o-rings are required for mounting the Piko on a handlebar. Put the screw
through the hole of the handlebar mount,
then put the second o-ring onto the tip of the
screw. The order of o-ring, screw, o-ring, hand-
lebar mount, lamp must be strictly adhered
to as shown in the picture in order to ensure
awless functionality. After that, tighten the
screw slightly rst, then securely. Cover the
open thread with the included plug.

Note: Basically, you may use the Piko lamp with all Lupine batteries irrespective
of the type (NiMH or Li-Ion). Usually, the battery life of old batteries is still acceptable, extraordinary dimming abilities provide good light even in case of a very
weak battery.
With the exible velcro strap, the
battery may also be mounted on
the frame.
Mounting
Put the clamp around the
handle bar and close.
Then tighten the screw
hand-tight with 4 Nm.

Note: The Piko control electronics not only controls high and
low beam; it also protects the rechargeable battery against deep
discharge and includes a low battery indicator.
Battery voltage
(once per Volt)
Battery voltage
(once per 1/10 Volt)
To switch o the lamp, keep the button pressed for more than
two seconds.
Note: The light outputs the maximum amount of light only if
airow lowers the temperature of the light suciently. If the
light is not cooled by airow, its power is reduced incrementally
to prevent the LEDs and electronic elements from overheating.
Lamp on
After connecting the lamp to the battery, the software runs a selftest; the
lamp itself as well as the red and blue LEDs in the switch light up once
The battery voltage is then indicated by the blue and red LEDs, as follows:
The blue LED ashes once for each volt; and then
the red LED ashes once for each 1/10 of a volt.
To display the battery voltage again, unplug the light from the battery
and then plug it in again.
Interpreting the voltage display:
More than 7.9 V: the battery is fully charged. 7.1 to 7.8 V: the battery
needs charging or is old. 6.5 to 7 V: the battery is not ready for use.
Note: To deactivate this display, simply press the button. In other
words, you needn't let the display go through its whole cycle in order
to use the lamp.
The control electronics measures the voltage under load.
Thus, measurements using a voltmeter will not be comparable.
Example: The blue LED ashes seven times and the red LED then
ashes ve times; this means that the measured voltage under load
is 7.5 V. This display helps you assess the actual state of the battery
prior to use.

Reserve power
Reserve power:
Note: The burn time remaining after the red LED is illuminated
depends on the total battery capacity, the ambient temperature and
the battery's age. Moreover, since the voltage curve of a Li-Ion battery
is not proportional to the power left in the battery, you need to learn
how to interpret the relevant displays for your specic battery. The
battery warning indicator may be programmed; see notes on setting
the light programs.
When the battery is discharged (the red LED has been ashing for some
minutes), the lamp ashes several times and is then switched o. After
switching the light on again (double click!), reserve power is available.
Depending on the age of the battery, some more minutes of light are
provided. To make reserve power last as long as possible, only light
below 2 W is provided. To indicate that reserve power is activated, the
red and blue LEDs ash in turn.
When reserve power is completely discharged, the light will be switched
o automatically. So slow down!
Warning! When the battery is completely discharged (the
red LED has been ashing for a few minutes), the light will be
switched o after ashing several times. Stop immediately!
The red LED indicates the state of the battery. If the battery voltage decreases below a certain value, rst the red LED is illuminated (the lamp
itself also ashes once) and additionally, shortly before the capacity is
entirely exhausted, it starts ashing.
Battery warning indicator:
Low capacity remaining
Blue LED on: lamp on
Red LED on: low battery, save power!
Red LED ashing: battery almost empty,
lights ashing: stop immediately!
Blue and red LED reserve power activated
ash in turn:
Explanation of LEDs:
Note: If the lamp is only used with 0.5 W and 1 W, reserve power is not available.
Warning: Do not switch on the light when the battery is
discharged, as this will invariably damage the battery.
Recharge the battery as soon as possible to avoid a deep
discharged battery.
Stop immediately!

You may easily select the Piko's light levels. Usually, the Piko operates in 3-level mode.
Two more light programs are available. They are very easy to select by simply keeping
the button pressed until the light ashes once, twice, etc. When taking your nger o the
button accordingly, the setting will be saved. (see programming scheme on p. 14)

Approximate power consumption of the light:
6 % dimming level 0.5 W 50 lumen
12 % dimming level 1 W 90 lumen
32 % dimming level 2.5 W 230 lumen
100 % 8 W 550 lumen
Default setting
Light levels:
The „Power Control System“ provides the possibility for individual programming.
By default, the Piko is set so that usually no changes are necessary.
Battery warning indicator:
The knowledge of whether „red" means that only for example 50 % or 25 % of the
capacity remain can only be gained from the experience of using the light. This also
applies to how much time is left when the red LED starts ashing. The default settings
are suited best for each battery for a long time.
Note: To determine the ideal indicator program for your application with another
battery or under extreme conditions, experimenting is indispensable. Should the
indicator of the battery high program not work to your satisfaction, switch to low
and test the behavior of the control electronics for some battery life cycles.
Battery
„High“
This is the default for Li-Ion rechargeable batteries. The red LED will light up very early.
Also reserve power will be activated earlier. If used with a NiMH battery, an extension
cord or in very cold temperatures, it might be advisable to change the program.
Battery
„Low“
This program is particularly suitable for older rechargeable batteries. The red LED and
also reserve power are activated with very little capacity left. This benets old batteries
with sucient capacity but with weaker voltage.
The battery warning indicator may also be altered. By default, the battery high program
is selected. The control electronics monitors the capacity of the rechargeable battery by
measuring the voltage. As battery voltage and capacity are not proportional, no generally
applicable information can be provided as regards the remaining battery life from the
point when the red LED is illuminated.
Note: If the battery low program has been selected, the lamp will ash twice when
connecting it to the battery. This ensures that the setting can always be determined.

Note: The numbers provided below assume that the lamp is switched on. When starting
with the lamp switched o, the lamp will ash once after approx. 2 seconds - lamp on/o.
Wiesel charger and three plug adapters
(for continental Europe, UK, and the USA).
Plug the included Wiesel charger into an
outlet and connect it to the battery.
Charging starts automatically, the green LED is illuminated.
When the battery is fully charged and the charger switches to Full, the green LED goes o. The
battery can be left plugged into the charger for an indenite period. Although this will not
damage the battery, it is not advisable for Li-Ion batteries since they do not require conservation
charging. When kept in a cool place, the annual self-discharging rate for such batteries is 15 %.
Note: The green LED is only illuminated during the charging process and will not come on if a
fully charged battery is plugged into the device.

Normally the plug contacts are maintenance free. However, if you use your Piko light in salty
environments, it is advisable to apply a thin layer of Lupine Dutch Grease to the contacts
every so often to prevent oxidation. Do NOT use terminal grease or contact spray.
Important! Always disconnect the battery from the light!
Otherwise the small amount of power used by the electronics will discharge the battery, and
the lamp may be switched on accidentally. The consequent uncontrolled heat buildup could
cause a re or melt adjacent plastic material.
If you intend not to use the lamp for a longer period of time, fully charge the battery and
leave it connected to the charger. For storing, we recommend a cool and dry place.
Important! Because of the delicate sealings, we do not recommend to open the lamp.
A leakage in consequence of opening the light is excluded from warranty!
