Don't be scared of the dark.

The darkest alleyways are no match for the Portland Design Works Cosmic Dreadnought 135 Headlight. Compact design and extended running time ensure darkness never wins.


The exterior case of the Dreadnought is built to withstand rain and snow so that leakage never stops you from riding. A Cree XPE LED bulb gives you a 135 lumen output for brightness that extends deep into the night; it is powered by two AA batteries for run times of 10 hours on high, 15 hours on low, and 25 hours on flash mode.


The Portland Design Works Cosmic Dreadnought 135 Headlight is adjustable to fit handlebars from 22.0 to 31.8mm in diameter. It weighs 91 grams with batteries, and it comes in the color Black.
