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. Each Hangover comes with a standard curved mount, and our Wide Mount that easily adapts to different curvatures.

Use as directed, when needed, and you'll be good to go.
A must have if you have a need for a ZDDP additive. This won't fix your worn valve seats, leaking piston rings, seasonal depression or gout but it will improve the lubricating properties of a quality oil in a properly maintained motor for your longevity goals.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.
