Can't say enough ..

About how this company stands by the community and by their products.. Just a week after they totally wowed everyone at the 24hrs of old pueblo race in tucson I contacted them because one of our hangover lights stopped working. Without any hesitation they sent me a return label for repair. No cost and no fuss later it was back on my helmet ripping through the desert. These guys are the best, to buy lights elsewhere is downright foolish.

#1 for a reason

The only thing better than the quality and performance is the customer service!

MTB at night.

Our group of riders love riding the trails just after sunset. The Hangover light was just the light I needed to be able to see out in front so I can anticipate and be ready for roots, rocks and switchbacks. Super light so you don’t feel the extra weight.

Baller helm light

The hangover light allowed me to get the KOM from my buddy after dark on a local downhill segment that doesn’t allow bikes. Thank you outbound!

Customer service 101

Just like the warranty page says, “ be honest about what happened to your light”.
So I literally head butted a tree limb and busted my HANGOVER helmet light.
Totally my fault. I didn’t duck low enough.
Outbound Lighting replaced it.
Unbelievable company and people!

Why build the best bike helmet light?

When we launched the Trail Edition back in 2017 it was a game changer for bike lights. A beam pattern specifically designed for trail riding with a wide evenly illuminated distribution. However we had lots of requests to build a helmet light instead of just a handlebar light.

So we got to work, figured out what is important for a helmet mounting, fine tuned the beam pattern and optimized everything else to come up with the lightest, longest lasting, and most powerful helmet-specific bike light out there.

Read on for more nerdy design details!

Helmet Specific Beam Pattern

When we developed Hangover’s beam pattern, we knew we wanted to better balance a narrow spot for throw down trail with a smoother transition to eliminate the tunnel vision you get from the off-the-shelf flashlight-style lights on the market.

We employ blended Total Internal Reflection (TIR) optic features to meticulously shape the beam from the high-intensity center with an even gradient to a soft fall-off covering all the peripheral around the rider, avoiding distracting beam artifacts while giving the rider a better sense of balance.

Check the slider comparison below to see the difference between a fine tuned optical instrument such as Hangover vs a name-brand light that has been around for years.

USB-C pass-through charging

Everyone has USB charging ports all over nowadays, so we make sure you can use any of them with Hangover, and not just some proprietary charger that you can only get from us. Even better, if you use a QC3.0-rated charger, you can get 85% charge in just one hour (24-hour racers rejoice!).

But we took that concept one step further and added Pass-Thru Charging to allow you full access to all output modes of your light while charging from an off-the-shelf USB Power Bank, so that you can extend runtime for those epic adventures, without limiting the light available to you (bikepackers rejoice!). We even customized the included USB-C cable with a right-angle connector to make cable routing on the helmet clean and easy.

Rock Solid Helmet Mounting

Helmets are like snowflakes, each one their own unique, ornate shape…that’s why we built Hangover with built-in tabs for standard “action camera” mounts, because they just work, and you don’t have to rely on some proprietary design from us.

We tucked the mount in low on the backside to keep the weight low, minimizing neck strain on long rides, and reducing the likelihood of low-hanging branches ruining your day…er, night.

Simple User Interface

Few people read instruction manuals, even fewer want to, so we keep our lights dead simple so that you don’t need an advanced degree to remember some complicated sequence of button presses get to the mode you want.

Hangover’s soft-touch overmolded top shell has a single, large button right in the middle that’s easy to feel through a thick winter glove in the dark, so you don’t have to hunt blindly around on top of your head just to turn it on.

Four simple modes cover the majority of use cases from set-it-and-forget-it pedally XC to long-climb-fast-descent Enduro rides – Adaptive / High / Medium / Low – and no SOS or seizure inducing strobes stuck in between.

Electrifying design

We like to keep our lights simple on the outside for the user, but that doesn’t mean we’re skimping on the guts inside. The constant-current driver maintains rock solid regulation through the Cree LEDs over the entire voltage range of the genuine LG 18650 cell with a unique battery monitoring algorithm to give you accurate feedback without interruption.

Complete with fast QC3.0 USB-C charging and Pass-Thru capability to boot, we engineer the electronics to maximize efficiency and runtime while minimizing charge times, all without any proprietary connectors that could leave you stranded. We’re always pushing the limits internally to deliver new feature sets that provide real value to the rider, not just fancy names.

Thermal Engineering

LEDs produce heat, they’re not magic, it’s just a fact. Getting the heat out of the LEDs efficiently without sending it into the rider’s hands is paramount for reliable and safe operation, so we pulled from our background in automotive lighting by employing magnesium for the thermal mass in Hangover to both reduce weight vs. aluminum and reduce the case touch-temperature.

Optimizing airflow across the cooling channels when riding sheds heat fast, allowing us to make the light smaller and lighter than competitors without requiring aggressive thermal controls in the firmware to throttle back output to keep the light cool. Of course, we have controls in the firmware for safety, the difference is you won’t need them on the trail with Hangover.
