Want a helmet light that is actually a light designed for helmets? Not just a flashlight? Then you've come to the right place.

Hangover borrows its name from the famous trail in Sedona, AZ (not the dreaded “brew flu”).

Into it, we poured every ounce of our automotive optics knowledge, creating the most compact bike light anywhere.

But slim does not mean dim. Some serious late-night thinking went into the Hangover, with countless hours prototyping the perfect beam pattern for trail riding and for helmet mounting. The resulting optics fills your entire field of vision with light, not just a narrow spot down the trail. So, you can avoid what you want to miss, and hit what you really want to shred.

Good for 90 minutes of strong output, with the ability to charge on the go, and yet only 100 grams. USB-C quick charge 3.0 is included as standard.

These lights are proudly and expertly made right here in Chicago, with the help of good coffee, homegrown talent, and a couple of dogs in the shop.

Adaptive Mode

What is adaptive mode? Nothing too fancy, it is just the default mode when the light is turned on. It stays on high for about 5 minutes, and over the course of 30 minutes it will very slowly reduce brightness to medium mode while your eyes ADAPT to the darkness.

Letting you get more runtime, without noticing a thing by tricking your brain.

All other modes are solid output so you know what you are getting at any time.

Mounting To Your Helmet

Helmets are like snowflakes, none are the same, and this makes mounting a challenge. We use tried and tested action camera mounts with 3M VHB tape. Here is a visual guide of the different types of mounts available.
