Product Information

Full details

The Exposure Lights TraceR 4 DayBright is an essential safety tool for daily commuters and road cyclists who prioritize high-visibility hardware in a compact package. This light offers a powerful 200-lumen output designed specifically for daytime visibility, providing peace of mind during heavy traffic. While its lightweight, CNC-machined build makes it an ideal choice for minimalist setups, users should note that the device requires a dedicated seatpost bracket for installation, which may limit mounting options on non-standard aero seatposts.

FAQs

How long does the battery last?

The light offers up to 40 hours of runtime depending on the mode selected.

Is the TraceR 4 waterproof?

It features an IP67 rating, meaning it is protected against dust and immersion in water.

Can I charge it with a standard phone cable?

Yes, as long as it is a USB-C cable, it is compatible with the device.

How do I know when it is finished charging?

The charging indicator on the light will reflect the status, typically turning solid once fully charged in 90 minutes.

Does it come with a mount for an aero seatpost?

The unit includes a standard seatpost bracket; compatibility with specific aero posts may require additional adapters if not standard circular shapes.

Troubleshooting

Light does not charge when plugged into USB-C

Check that the cable is fully inserted and try a different wall adapter or power source to rule out a faulty charger.

Light is not as bright as expected

Verify that the mode is set correctly to DayBright pulse rather than a lower-intensity steady mode.

Unit clicks loosely in the mount

Inspect the bracket for road grit and ensure the mounting interface is clean and properly aligned with the seatpost.

Pros and Cons

Pros

  • Extremely lightweight at only 35 grams
  • High-output daylight visibility pulse mode
  • Durable aluminum construction
  • Fast 90-minute USB-C recharge
  • Excellent side visibility for safety

Cons

  • Requires specific seatpost bracket mounting
  • No quick-release clip for non-post mounting
  • May not fit wider or non-round aero seatposts

Setup, Compatibility & Care

To install, attach the included seatpost bracket securely to your bike. Ensure the light clicks firmly into the mount to prevent vibrations during rides. For maintenance, keep the USB-C port clear of debris and ensure the port cover is properly seated after every charge to maintain the IP67 seal. Avoid using harsh chemical cleaners; a damp, soft cloth is sufficient to wipe down the aluminum body after particularly wet or muddy rides.
