If you’re still not using daytime running lights while out on the road, it’s probably time to start. According to an ongoing research partnership between Trek and Clemson University, the use of daytime running lights are linked to a 33% reduction in accidents between cyclists and cars. Not to mention that a flashing rear light apparently makes a cyclist a whopping 270% more recognizable to drivers. With numbers like that, it’s pretty motivating to slap a light on your bike before you head out the door. And to make that process easier, Bontrager has unveiled a new line of RT Daytime Running Lights with more power in a smaller form, plus a number of cool features.

Flare RT

Representing an update to the popular Flare R, the new Flare RT is 36% smaller, 30% more powerful, and has 20% more battery life. Additionally, there is a new USB charging port that features better IPX7 waterproofing, a built in light sensor to adjust the lumens based on the ambient light conditions, a lock mode to keep it in the preferred setting, and Blendr integration to fit on products like the new Bontrager Circuit MIPS, or the new Trek Madone seatpost. Additional features include a specific interruptive flash pattern with a maximum 90 lumen pop to get drivers’ attention, and ANT+ compatibility to allow control with your Garmin, GPS, etc.

The light integration on the Bontrager Circuit is actually pretty interesting, as the Blendr mounts are magnetically attached to the helmet. That means you can attach any Flare light to the mounts, then snap them on or off the helmet using the built in magnets. As long as the lights are small like the Flare series, the magnets firmly hold the lights in place, but should you crash, they’ll easily pop off to prevent injury from snagging on an object during the crash.

Weighing in at just 33g, the Flare RT alone runs $59.99.

Ion 200 RT

To match the Flare RT, the Ion 200 RT includes all of the same features, just in a compact 32g package with 200 lumens of light for the front. Both lights are said to be visible from 2km away and have been optimized for daytime use. You can buy the Ion 200 RT for $59.99 each, or you can get a Flare RT/Ion 200 RT package for $114.99.

Ion Pro RT

The third addition to the line up is the Ion Pro RT. While the other two are definitely “to be seen” lights, this one has “to see with” kind of power. Featuring 1300 lumens of maximum power out of the Cree LED, the light comes in at 183g for $99.99. You can also buy it as a package with the Flare RT for $154.99.

  1. Should the specs include bothersome details like lumens and runtime (per setting) for the Ions? Otherwise, good coverage.

      200LM-1.5hrs, 100LM-3hrs,5LM-14.5hrs, Night Flash-30hrs, Day Flash-12hrs

  2. I can verify that the current version of these lights in daytime flash mode are amazingly bright and incredibly effective in grabbing people’s attention. I have had many instances of drivers crossing my path that were looking the other way or not really paying attention and I could see their head snap to my attention as they catch the flashing from the corner of their eye. In fact I run the flash mode day or night, never steady mode, because the extra safety of the super bright flashing is so important for being noticed from further away. I consider these lights more important than wearing a helmet, because any collision with a car is not likely to end well, helmet or not.

    The flare has tons of battery life in flash mode. The current ion however has too short battery life in flash mode (about 4 hours vs claimed 10). I highly recommend getting the ion pro for the extra battery life.

    • Nope. You need to know the angle(s) of the light cone or the area illuminated at a known distance. From that you can calculate an average lux (lumens/m^2), but it’s better to sample illuminance (units= lux) at different points across the diameter of the illuminated area.

      In practical terms, there’s no way to come up with a rule of thumb given how design (or lack thereof) of lights and their components–light source, reflector, lens–varies from manufacturer to manufacturer and from model to model. Some companies actually invest in real optical engineering while others, well, don’t do as much.
