You asked for it, and we have delivered. A self-contained light designed specifically for mountain biking and helmet mounting. Named after the famous trail in Sedona, AZ.

  • 100g total weight with integrated mount.
  • 90 minutes of strong output, with the ability to charge-on-the-go.
  • 0-80% charge in 1 hour with standard USB-C.
  • Incredible beam pattern designed with helmet mounting in mind.
  • Ultra-slim form factor.

In our effort to continuously improve our products, we acted on a lot of the issues raised in earlier reviews when we launched Hangover in late 2019. The reported hum was fixed with a software update, we have updated the material for the USB door so it stays closed better, we updated our runtime numbers and provided an exact runtime chart along with updating the modes to better understand the exact runtime that is expected.  Any customer with an older light that has these issues can contact us for an exchange!

We know what you want from the best helmet mounted bike light. Lightweight, ultra-slim form factor, incredible output, easy to use,  and being able to recharge quickly is always a plus. So we did just that and developed the Hangover.

A helmet mounted bike light designed from the ground up to be exactly that, no bulky adapters, no wires, no nonsense.


This is how we did it: 

For starters, we developed the optic in-house, from the ground up.  You can’t have a great light without a great optic, so we put hundreds of hours into simulation and prototypes to develop a beam pattern that fills your entire field of view with the light you need, not just a spot down the trail.



The blended TIR optic uses precision engineering to finely tune the beam shape, eliminating the typical “round hotspot” edges by redirecting portions of the beam to where you need it most, creating a dramatically smoother beam.  Creating a Light Carpet around your periphery allows you to see and react to the whole trail and not get “tunnel vision” with harsh edges.  The smoother the beam, the less strain on your eyes, the better you can see and the more comfortable your night ride is.




Then we focused on packaging. We absolutely wanted this to be the slimmest and lightest light on the market. So light you don’t even notice it on your head. So we put the battery sideways, used lightweight magnesium for the heat sink, lightweight PMMA with integrated overmolding for the lens, and an over-molded polycarbonate shell to form the top half.

The result is an incredible 100 grams total weight. Absolutely unheard of for a high power light.

Combine that featherweight with the fact that we can run this light at 100+ minutes of usable runtime and you start to wonder what else you could possibly need. Need to last longer than that? We are one of the only bike lights on the market that offer pass-through charging. So you can hook up any USB powerbank you may own and it will supplement the light as your ride goes on. Giving you unparalleled flexibility for your specific riding needs.

Let’s talk about runtimes for a second. The bike light industry tends to like to use the FL1 standard, which rates runtime as the time it takes to go from full brightness to 10% output, an outdated measure that harkens back to the days of using Alkaline batteries, and when you would swap out your flashlight battery… But this is 2020. We need to get real about runtimes. Nearly every single light on the market starts out full brightness and diminishes over time, and this is okay. Our eyes adapt to the darkness and as long as the reduction is gradual, we literally cannot tell the difference until reaching about 50-60% of the perceived brightness.  Which is why we say that we have 100+ minutes of usable runtime in our standard Adaptive Mode, we aren’t going to call this “high” anymore and have a mode that isn’t actually high…. we made that mistake once.

Here is the expected runtime chart. This should be far more useful then just a single number. Also included is one of the more popular bike lights out there to reference how the typical “1 hour runtime” is advertised versus how it actually performs.

Our High, Medium and Low Modes are SOLID output modes that are designed for the rider that changes the light intensity often. Low and slow for the climbs, maximum output for the fast descent. Medium is the perfect setting when paired with the Trail Edition or another Hangover on the handlebars to get nearly 3 hours of runtime.  Adaptive is for the rider that hits the trail hard right from the parking lot and doesn’t want to think about changing output often. Just set it and forget it and get 90+ minutes of runtime.

Every mode has a 20-minute reserve that drops to low, we don’t want you getting stuck in the woods with no warning, or no way to get out in time. Plus let’s be honest, if you left it on high you probably were really only going to get another 3 minutes of runtime before totally going out, so lets put in a safety measure…


No excuses anymore: Charge to 80% in 1 hour

Think for a second, how many times have you or a friend said “I can’t ride tonight, I forgot to charge my lights.”  Typical bike lights take 3 hours to charge IF you paid for the “fast charge” feature, 6 hours if you didn’t.

With the Hangover, you can get an hour of runtime in just 30-40 minutes with a compatible QC 3.0 charger, and a nearly full charge in around an hour thanks to standard USB-C QC charging.  That means you can plug it in while you’re getting ready, or driving to the trail, and be ready to go.



American Made Quality.

Like the Trail and Road Edition, these lights are built in our Chicago workshop. We put a massive amount of engineering work into making sure we can assemble our lights quickly, accurately, and with the highest quality to ensure that we keep production stateside for years to come.  Backed with a no-questions-asked warranty and amazing customer service. We want you to be a customer, a friend, and an Outbound rider for life.

As a self-proclaimed “analysis paralysis” consumer, this company and their lights bring a lot to the game to be an easy choice. I was in the original pre-order group to receive the first batch of the Hangover and have ridden with this for several weeks (morning rides @ 20*-30* temps, 5 days a week). Here are a few key points that make this a grab and go for the next night ride: Whether you use this as a primary or with a bar mount, the incredible beam throw lights up things hundreds of yards down the trail… turn your head and the world lights up (even in the medium setting). The beam color is also neutral enough to allow your eyes to immediately pick up on upcoming obstacles. Solid construction & great fit/finish, intuitive/simple output selection. Fast charging and the external battery pack pass-through option is killer, it’s light weight, temps stay cool, and seem to be well managed. The “gopro” mount system allows for many options and looks to be robust. Finally, this company is operated by an light-engineer who gives a damn about quality output (not just raw numbers) and is currently small enough to be quick on their feet to take feedback and respond quickly. There are a few things to keep in mind that aren’t all “rosy.” As a new company, there will be some growing pains as they continue to tweak the product to be better. As far as I can tell from this first batch, there are 3 “real” settings (high, med, low) and if you’re going to be in the dark for more than 1 hour, plan on using the Medium mode to start with (it actually has decent illumination). High mode is fantastic for risky/tech sections but, will burn through the battery quickly if left on all time. It seems that “sometime” after 1 hour in it'll drop to low. This then leaves you only with the lower illumination to get you through the next rowdy section and/or home. If your normal ride is less than 1.5 hours, this is probably all moot. Maybe a higher amp hour capacity battery would help. While the beam throw is wicked long and “hot,” I’d like a little better light transition between the center and peripheral sides. Looking at the horizontal 6 emitters & website beam shots, I assumed this was going to be as wide as their trail edition without the hassle of a cord (maybe I’m too picky). The thick under carriage rubber port cover doesn’t “positively” close… although it does return to it’s original straight orientation. In conclusion: This company looks to already be tweaking the product to be better (software/run-time/rubber door) and this is a nice piece of kit that should last for years. While my current light from the first batch may have some short comings; they can be dealt with and forgotten when you’re enjoying the next ride with friends. As I hear, the owner is willing to exchange those from the first batch for a future updated one… Here’s to a company that builds a great product and gives a damn!

Excellent light!!

I had high expectations for this helmet light after doing a lot of research and reading reviews. I am here to tell you that it did NOT disappoint. This light was brighter and worked better then my buddies 1600 lumen handlebar light with external battery. Pairing this with the trail light I have coming from Outbound will be a awesome combination!!!

Best light ever!!!

First off, the light is fantastic. Provides plenty of light, with a wide range of glow, almost don't need a bar light at night. In fact, the other night my bar light died, and I rode home a few miles in the dark trails of AZ with just the hangover and had no issues. And second, Alex is fantastic to work with. Great customer service.


Ok so here's my honest review of this great helmet light. So I rode it last night on a trail that usually takes me about an hour and fifteen minutes where there are times I used it on low because on this particular trail, there are some street lights, so no need to keep it on high the whole time. That's usually around the beginning but sometimes I would power it up to high as I would come across total darkness. I figured I would do it that way since I really need it on high mostly towards the end of the ride.
This is light is amazing at how it projects out. This really helps me because there's a hill I like to bomb down and with this light I can clearly see down the path pretty far. I use the outbound trail light for my handle bars and it's the perfect combo. I truly love these lights!
So now here are the things I didn't like. When I received the light, they were kind enough to send me a helmet mount with the straps because I have an old helmet with the big holes. It was identical to my old niterider helmet mount but the straps didn't have the locking mechanism so after trying to figure it out, I just took the straps from my niterider mount and it worked perfectly. Not too big of a deal.
The deal breaker for me in which I'm sadly thinking about returning the Hangover was that during the last part of my ride when I really needed it to be on high, it powered down to medium, which is still ok but I'm being very picky about that and wished it stayed on high.
This is advertised to stay on for 90 minutes and I thought I could make it last by keeping it on low for parts of my ride but in a little over an hour, it powered down.
Anyways, I'm on the fence right now and I hope they fix it to where the battery is guaranteed to last on high for the 90 minutes they advertise.


Great light. Very focused on what you point it at. Worked great riding technical trails. You do have to manage it depending on the length of your ride. Thank you.
