About this product
The
Commuter Pro RT
has an anti-glare beam to provide light exactly where needed, and not into
oncoming traffic. This light is daytime visible from 2km.
The Bontrager Flare RT
adds safety as a rear daytime running light. Both are rechargeable and remote
controllable when paired with our Transmitr Micro Remote.
The front light is very bright. Do not stare at an operating front light. Staring may be harmful
to the eyes.
WARNING:
The front light may be hot and could cause a burn or damage material it may contact.
Do not activate (turn on) light in enclosed area.
WARNING:
Do not use if the battery is impacted. Also do not puncture, crush, deform, disassemble, or heat a
lithium-ion battery above the permitted temperature. Inflicted damage to the battery may result in a fire,
explosion, or coming in contact with specks of lithium or lithium dust.
WARNING:
IMPORTANT:
Check your local lighting laws. Flashing lights and full brightness may not be allowed in all
locations. These lights do not conform to the German road traffic regulation StVZO.

A bicycle without correct lights and reflectors might be difficult for other people to see, and you
might not be able to see them. If you cannot see, or other people cannot see you, you could have an
accident. Make sure your lights are set up, operating correctly, and that batteries are charged.

Battery charging and care
(see Table 3)
Both the Commuter Pro RT and Flare RT were charged prior to packaging, but we recommend that you
charge them before first use.
To charge the battery
IMPORTANT:
For best results, charge at room temperature in a dry place.
Use a certified CE or UL approved USB-C cable rated for 2Amps
or greater. Avoid extreme conditions including wet, cold, or extreme heat.
Note:
If the main button indicator is flashing red while plugged in, the light
is either too hot or too cold to charge. Charging will begin when the light is
between 32˚ F and 104˚ F (0˚ C and 40˚ C).
1. Open the USB port cover.
2. Plug the USB-C cable into the USB port on the light.
3. Plug the cable into a wall adapter.
4. When the charge is complete, unplug the USB-C cable and close the USB port cover.
IMPORTANT:
Ensure the USB cover is latched before riding in rain or in wet conditions. If the USB cover is
not closed, damage to the light may occur.

The left row of lights will show:
• One red light when below 20%
• One red light flashing when 5% or below
NOTE:
When below 5%, the modes and settings will be disabled.
Low battery feature Flare RT
When the battery has fallen below 20% life, the bottom LED will flash red.
Caring for the battery
• Store the light at room temperature in a dry place. Avoid moisture, or extreme hot or cold.
• Store the light in a charged condition. Battery life will decrease if the battery is stored in a fully
discharged condition.
• Over time, the run time of the battery will diminish. Expect about 500 full charges, depending on
care. After a full life, the battery will continue to charge but with a lower run time. When the run time is
unsatisfactory, do not open the case of the light or incinerate; please recycle.
Traveling with the battery
When traveling by air, verify with your carrier how lithium ion batteries of this capacity must be treated. Often
these lights need to be packed in carry-on luggage.
Protection
These lights are designed and tested for use in all riding conditions and have an ingress rating of IPX7.
Lights are not intended to be stored outdoors and should be stored indoors after use.
