Bontrager’s Ion 1.5 proves that bright things come in small packages. It makes you visible in the dark with a super-bright, environmentally friendly .5-watt LED that's visible from 2,000 feet away with 270 degrees of visibility for serious safety. It'll give you 80 hours of run time on flash mode, and 45+ hours on steady with the included AAA batteries. It comes with an adjustable mount that fits bars from 22.2-31.8mm.
Run time: 80+ hours
