DISCOVER THE NIGHT!
Thank you for choosing the Evolution™ system from NiteRider,
the innovator in technical lighting systems. The Evolution is an
easy-to-use, high-intensity halogen system that can be
mounted to the frame or helmet.
To get the most from your NiteRider light, we urge you to
familiarize yourself with the following safety and operation
instructions.

1
PROTECTING
YOUR INVESTMENT
When not in use, always disconnect the headlamp from the
battery. To unplug, grasp the connector, not the cable.
Properly charge your battery to maximize its lifespan (see
“Battery Charging and Care” on page 10). To avoid damaging
your system, only charge your NiteRider battery with the
appropriate NiteRider charger.
While the Evolution will perform in wet weather conditions,
submerging it in water will damage the system. If you need a
submersible light, NiteRider manufactures industrial-grade
dive light systems. For information, contact NiteRider Dive
Lights at 858.268.3850 or visit www.niteriderdive.com.
RIDING AT NIGHT
While the Evolution will improve your control and enjoyment of
night riding, please remember that cycling at night is an
inherently dangerous activity. In addition to using your lighting
system properly and riding with extreme caution, NiteRider
urges you to:
• never ride alone
• always let someone know where you are going
• wear a helmet and reflective clothing
• carry an auxiliary light and emergency supplies.

QUICK START
1. Charge the battery for nine hours before the first use. To
maximize the life of the battery, it is important to disconnect
the battery from the charger immediately after charging.
See “Using the 9-hour Overnight Charger” on page 10.
2. To mount the headlamp and battery, see “Mounting the
Headlamp” on page 6 and “Mounting the Battery” on
page 8.
3. Connect the battery to the headlamp or helmet cord.
4. To turn the lamp on and off, press and release the
headlamp power button.

MOUNTING THE HEADLAMP
The Evolution headlamp can be mounted to the handlebar or
a helmet.
Universal Handlebar Mount
The Universal Handlebar Mount (UHM) is designed to fit on
virtually any handlebar. Included with the mount is a 2.5-mm
Allen wrench, a pair of black rubber bumpers already in
place, and a thin rubber shim to customize the fit on large
handlebars up to 32 mm in diameter.
Turn the knob counter-clockwise, allowing the hinge to swing
open. Place the mount on the handlebar on the left side the
stem, orienting the rectangular notch in the slider clip to the
rear. Swing the hinge down to make contact with the
handlebar. Swing the hex bolt up, seating the knob into its
recess. Turn the knob clockwise to tighten and secure the
mount to the handlebar.
The UHM can be adjusted to accommodate any handlebar
angle. By loosening the 2.5 x 30 mm Allen screw, you can
move the swing arm back and forth to straighten the
headlamp. Tighten the 2.5 x 30 mm screw after the
adjustment.

To pivot the headlamp, loosen the 2.5 x 12 mm screw located
under the slider clip and swing arm and rotate the headlamp
to the desired position. Make this adjustment before
tightening the 2.5 x 30 mm screw.
Helmet Mount
1. Unclamp the straps on each side
of the helmet mount and pull
them free.
2. Position the plastic mounting
plate as close to the centerline of
the helmet as possible, orienting
the parallel grooves on the slider
clip to the rear.
3. Feed each strap into and out of
two helmet vents, circling each
strap back to the upper edge of
the corresponding clamp.
4. Fasten the straps by inserting
them into the clamps.
Inserting the Headlamp into
the Handlebar or Helmet Mount
Insert the headlamp mount into the handlebar or helmet
mount slider clip from the rear of the slider clip forward.
Gently rocking the lamp as you slide it may help. Do not push
the release lever when inserting the headlamp into the slider
clip; let the lamp snap into place by itself.
To remove the headlamp, push the release lever and slide the
lamp backward.
Note
: After mounting the headlamp, adjust the headlamp so
it illuminates the road properly without distracting oncoming
riders.

MOUNTING THE BATTERY
The battery can be mounted to the bike frame or placed in a
jersey pocket, hydration pack, or fanny pack.
Warning
: For safety reasons, a cyclist should never be
tethered to the bike. If the headlamp is mounted to the
helmet, do not mount the battery to the frame. Conversely, if
the headlamp is mounted to the handlebar, do not place the
battery in a pocket or pack.
Frame Mount
1. Thread the wide Velcro tie
through the slots on the top of
the battery clip.
2. Attach the concave surface of
the battery to a safe, convenient
location on the frame (typically
under the top or down tube),
placing the Velcro strap over
the tube but under any shift or
brake cables.
3. Secure the handlebar cord to
the frame using the thin Velcro
tie. Make sure the cord does
not interfere with any moving
parts.
Pocket or Pack
1. Route the helmet cord through a
helmet vent or along the outside of
the helmet using the thin Velcro tie
to secure the cord.
2. Connect the helmet cord to the
battery, making sure the cord does
not interfere with any moving parts.
3. Simply place the battery in a
pocket or pack.

9
OPERATION
1. Connect the battery cord to the headlamp or helmet cord.
2. To turn the lamp on and off, simply press and release the
headlamp power button.
Warning
: To protect the battery from over-discharging, turn
off the lamp before it reaches complete darkness.

10
BATTERY CHARGING
AND CARE
Rechargeable batteries can last years with proper care. Most
importantly, fully charge your battery:
• before the first use
• after each use
• before storing
• every 45 to 60 days when not in use.
Using the 9-hour Overnight Charger
To maximize the life of the battery, avoid overcharging it.
Estimate the depletion of the battery and charge it according
to the following chart:
Usage Charge Time
30 min 1 hr 30 min
1 hr 3 hrs 30 min
1 hr 30 min 5 hrs 45 min
2 hrs 7 hrs 30 min
2 hrs 20 min 9 hrs
It is very important to disconnect the battery from the charger
after the above charge time has elapsed. Setting a timer may
be helpful to avoid overcharging. When disconnecting the
battery and charger, grasp the connectors, not the cables.
It is also important to avoid over-discharging the battery.
When operating the light, turn the lamp off before it reaches
complete darkness.

11
Battery Initialization
Until the battery has been charged and discharged up to ten
times, you may experience shorter than expected run times
as well as higher than normal charger and battery
temperatures.

12
RUN TIME
The Evolution will run for 2 hours 20 minutes on
a fully charged battery.
Run times are approximations and will vary.
