1. Trek Ion 200 RT/Flare RT

A compact and powerful light set with multiple flashing light patterns for daytime visibility from up to 2 km away. Specific flashing, focus and beam width settings ensure ultimate visibility during the day. The Flare RT rear light ensures maximum visibility on the road, in the city and on the cycle path. Thanks to high-performance LEDs from Cree, the Ion 200 RT generates 200 lumens for optimum visibility. An integrated light sensor automatically adjusts the brightness to your surroundings. Can be paired with compatible ANT+ devices for automatic switch-on, battery status display and wireless operation. Can be easily attached to handlebars, helmet or directly to the bike. Includes Ion 200 RT, Flare RT, Quick Connect mounts and micro USB charging cable. 

2. Trek Ion

A compact and USB-chargeable headlight that can be easily attached to any handlebar. Thanks to focussed optics with a wide yet bright light beam, you will no longer be overlooked. The integrated light sensor automatically adjusts the brightness in flashing mode. The light duration is 1.5 hours at 100 lm, 3 hours at 50 lm, 16 hours at 5 lm, 7 hours in night flashing light and 8 hours in day flashing light. It is supplied complete with Quick Connect bracket and micro USB charging cable. A Blendr-compatible, secure handlebar mount is available separately. Research shows that using a flashing rear light that is visible in daylight is the most effective way to increase the likelihood of being seen by motorists. Studies have shown that riding with a flashing daytime running light is the measure to increase the visibility of cyclists. With a flashing rear light, your visibility during the day is up to 240 % higher than that of cyclists travelling without a rear light. Not all lights are the same. A true daytime running light has a concentrated focus, a conspicuous flashing pattern and a long range so that it can be seen from a considerable distance during the day. Without these three characteristics, it is just a normal light. When the battery power drops below 5 %, the light output is also reduced to significantly extend the remaining battery life.
