HEAT SINK AND COOLING SYSTEM
The high powered output of the TSL-2500 creates a
lot of heat. The cooler the LED’s run they will have a
longer lifetime. Your light will also produce more light.
To reduce the heat generated by the running LEDs, the
TSL-2500 was designed with an aluminum alloy body
and equipped with Serfas’ Ram Air cooling system.
The Ram Air cooling system lets air flow through the
light body when riding.
As a precaution, do not run light while bike is
stationary. To properly cool the unit, it must
have airflow.
Copper plate LED board
increases the LED heat
transfer rate and enhances
the light’s performance.

HANDLEBAR MOUNTING HELMET MOUNTING
To adjust the horizontal beam, spin the headlight
left to right for your best side to side beam angle.
To adjust the vertical beam angle, loosen the
mounting and rotate the light up and down to
your best vertical beam angle, then tighten
the mounting.
UNIVERSAL BRACKET INSTRUCTIONS:
Open bracket by pulling thumb lever down, then unclip the
thumb lever from the cam hook to open. Adjust the rubber
strap length to fit bar by moving the strap up or down the
rungs located under the swivel light mount. Once the length
of strap is adjusted for best fit, install around handle bar or
seat post by inserting thumb lever into cam hook, then
rotate thumb lever upwards towards swivel mount to lock.
If light still moves on the bar open thumb lever and shorten
strap by moving the rubber strap up to the next rung.

2. Put helmet mount in desired location on helmet (top center works best).
3. Insert strap through nearest air vent on top of helmet and loop around
inside of top of helmet to the next closest vent to the open strap hole on the
helmet mount.
4. Put hook and loop strap through open hole on helmet mount and pull snug

HEAD LIGHT OPERATION OVERHEAT PROTECTION
POWER BUTTON
3. Press and hold the on / off button around 1 second to turn
off the light.
4. When the indicator on the power button goes from solid blue
to blinking red the battery has 20% or less charge remaining.
OPTIONAL TL-80 TAIL LIGHT OPERATION (SOLD SEPARATELY)
1. Your new light has four brightness settings (over drive,
high, medium and low). Simply press the power button to
turn on.
1. Plug connector from tail light into connector A on figure 1.
2. When plugged in the TL-80 functions based off of the setting of the head light.
3. Off switch on TL-80 is only used to turn tail light on or off.
The overheat protection circuitry in your light ensures that
it operates at safe temperatures to insure a long life.
Continued heat build up is the biggest enemy of LED’s 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 “Standard” mode. Once the air flow
over the light has improved and the running temperature is
reduced the circuitry will kick the light back into the
previous mode.
2. With each additional press of the power button the light will cycle
through its modes.

REMOTE SWITCH BAT-4 BATTERY OPERATION
It is normal that the battery may reach high temperatures during charging (up to 104°F/40°C), as there
is a chemical reaction happening in the battery.
Several factors can influence the battery’s durability and lifespan: type of cell strain, the maintenance
routine, the temperature and etc.
The battery capacity may become less effective; having about 80% of its capacity after 300-500
charge/discharge cycles. The battery may have 3 years or more life span under good care.
The battery voltage and capacity decrease at low temperatures, especially near or below freezing point.
The capacity decreases 5% - 10% at freezing. Around 0°F, the capacity decreases 30%. The battery
performance will return normal when the temperature gets to 70°F/20°C.
The battery will lose around 1% of its capacity per day when you store the battery at normal room
temperature. Battery temperature should never exceed 104°F/40°C, it will lose about 5% of its capacity
per day.
Fully charge the battery before storing. When not in use, we suggest a cool and dry place for storage.
Li-Ion batteries are volatile. Failure to read or follow the instructions may result in fire, personal injury or
damage to property. Do not leave batteries unattended during charging or use. Dispose of battery pack
properly if there is any noticeable damage to casing.
Equipped with a remote switch, allows you easier
on the fly control of your light. You can mount the
switch close to the grip area of your bars so that
your hands don't have to leave the bar to change
settings. It is also mountable on your helmet for
easier to reach control.
1. Open the rubber cap on the back of the light.
2. Then plug in the controller wire.
3. Make sure it has been completely connected.
1. Put one of the ends of the hook and loop strap
around the handle bar.
2. Align to the controller button and pass through
open eyelet on switch base.
3. Pull the hook and loop ends tightly.
1. Put one end of the belt go through the helmet hole.
2. Align to the controller button and pass through.
3. Pull the hook and loop ends tightly.
* When unused, please ensure the protective cap
is closed to avoid water getting in the light body.
