About This Product

The Commuter Pro RT features an anti-glare beam designed to direct light precisely where needed, avoiding oncoming traffic. It is visible in daylight from up to 2km. The Bontrager Flare RT serves as a rear daytime running light for added safety. Both lights are rechargeable and can be controlled remotely when paired with the Transmitr Micro Remote.

⚠️ The front light is very bright. Do not stare at an operating front light, as it may be harmful to the eyes.

⚠️ The front light may become hot and could cause burns or damage to materials it contacts. Do not activate the light in an enclosed area.

⚠️ Do not use if the battery has been impacted. Do not puncture, crush, deform, disassemble, or heat a lithium-ion battery above the permitted temperature. Damage to the battery can result in fire, explosion, or contact with lithium dust.

⚠️ IMPORTANT: Check your local lighting laws. Flashing lights and full brightness may not be permitted in all locations. These lights do not conform to the German road traffic regulation StVZO.

Battery Charging and Care

Both the Commuter Pro RT and Flare RT are charged prior to packaging, but it is recommended to 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 wet conditions. If the USB cover is not closed, damage to the light may occur.

Commuter Pro RT Battery Charging and Care

• Left row: Commuter Pro RT battery level indicator.
• Right row: Blank when charging.
• Top light will flash until charged.

• When fully charged, the five green lights stay on for 1 minute, then turn off.
• When plugged in after the battery is completely discharged, it may take a minute for the LED indicator to turn on indicating a charge is occurring.

Flare RT Charging Status Indicator

The status LED indicates the percentage of battery charge remaining.

Low Battery Feature

• Commuter Pro RT: 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%, modes and settings will be disabled.

• 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 stored fully discharged.
• Over time, battery run time will diminish. Expect approximately 500 full charges, depending on care. After reaching its full life, the battery will continue to charge but with reduced run time. When run time is unsatisfactory, do not open the case 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.
