Ion Front Bike Lights

Be seen (and see, too)

Whether you’re lighting up your local trails after dark or looking to stand out on your daily road ride, Bontrager has the light for you. Turn to our more powerful front lights like the Ion Elite R and Pro RT for trail-riding, and go for the more compact Ion 200 RT and Ion 100 R for added visibility on any ride.

Daytime Running Lights

Research shows riding with a flashing, daylight-visible light is the single best way for a cyclist to increase the likelihood of being seen by a driver.* Bontrager Daytime Running Lights (DRLs) are designed with a specific flash, focus, and range to make them more visible during daylight hours.


Most standard bike lights use a steady flashing pattern, but lights that vary the frequency and intensity of their fash pattern are often more noticeable. The Day Flash setting on our DRLs uses an interruptive flash pattern with accentuated Lumen pops that are more noticeable during the day.


We intentionally amplified the output of our daytime-visible lights to intensify their beam and extend its range. Without this amplification, a light may appear bright in your hand but won’t be noticed by motorists out on the road.


The earlier a rider is seen, the more time a driver has to react and pass safely. Our DRLs are detectable from a greater distance than other lights—every model is visible from at least 400m away, and select models are visible from over 2km away.

Bright ideas

Bontrager Ion lights are packed with features that make them great for everyday use on the bike. Look for the following features throughout the Bontrager Ion family.


If a Bontrager light has “R” in the product name, it’s rechargeable. All Bontrager Daytime Running Lights include a micro USB cable for hassle-free charging.

Battery indicator

The built-in LED indicator light glows green for full charge and switches to red when you’ll need to charge up again.

Flash and steady modes

Multiple flash and steady modes let you dial in the best option for your conditions, day and night.

Blendr integration

Carry your Ion lights on your bike, on your helmet, or both! Blendr compatibility lets you seamlessly integrate Ion lights with Blendr-compatible Bontrager stems and helmets.

Wireless connectivity

All Bontrager lights with the RT surname have wireless connectivity. Control your lights (and even set them up to power on when you start riding) by pairing them with Bontrager’s RIDEtime Elite computer, certain Garmin units, or Bontrager’s Transmitr remote.

MTB lights like Bontrager Ion Pro RT offer powerful, long-lasting lumens that light up the trail so you can adventure confidently even after the sun sets.

Lumens that last

Bontrager Ion front bike lights outshine the competition with consistent brightness and meaningful power that lasts.

Compact and powerful

Ion’s compact and simple design is ideal for mounting on your helmet or handlebars, and it gives you maximum runtime without an external battery, cable, or wires.

Truth in Lumens

Bontrager Ion lights have truthful Lumen output ratings. They're indicative of the light output you'll actually see on the road or trail for the majority of the runtime, instead of the FL1 industry standard of measuring output 30 seconds after powering on.
