Brightz GoBrightz LED Bike Frame Light - 4 Modes for Flashing or Constant Glow - Fun Safety Light Bike Accessories for Kids to Adults

These lights are marketed to a younger audience with the prospects of adding that dope early 2000's custom import scene underglow lighting to their bicycle, increasing their visibility, safety, and aesthetic appeal. However, even if you're a jaded adult cyclist, there's more than meets the eye and there may be something in it for you.If you have a cargo rack on your bicycle, this is the perfect taillight. Mounts easily and securely to the rear with two zip ties, and lasts long enough for multiple night rides. Stuff two AAA's in a Ziploc bag, put it in your pannier bag, and enjoy the piece of mind that you can quickly swap them out without tools should the light start to die out on you.Lighting options include solid light and three flashing modes of increasing frequency. The LEDs shine bright, and in a horizontal position facing directly behind, is nearly impossible to miss in the dark.I've had a handful of these lights since middle school, and the first few did succumb to corrosion after lots of use and sitting exposed to the winter elements. However, the two I have now (the oldest being a few years old) still work fine despite exposure to the elements. I highly recommend installing with the battery cover facing down so as to drain any water that enters. This makes replacing batteries a little more cumbersome, but it's still very easy and quick to do on the side of the road, and the batteries last surprisingly long for only two AAAs so unless you do consistent riding in dark/inclement conditions, you shouldn't have to replace them too often. I've had the same batteries in mine for a few months, and they still shine bright after some hours of night riding.Even if I had to replace the whole unit every year, it would be well worth the ~$12 for the utility, ease of installation and use, cheap price, reliability, battery life, and visibility. Brightz is making a mistake by not marketing their red bar light to commuters and bikepackers considering how perfectly this fits on a rack.

In my second riding season with this light set. I already have very bright front and rear LED's on my commuter E-bike. I mounted this light on the top tube because the down tube is where the battery sits (too fat around). The silicone mounting straps survived a full summer of riding. No stretching, fading or significant wear noticeable. The two AAA batteries lasted all summer and into the fall. I just replaced them but they were working fine. Still plenty bright. I just wanted a fresh set for 2025. The yellow LED's give a sharp contrast to my white front lights and red rear lights. VERY VISIBLE. No complaints here. Bring on the Spring!

Nice and bright, just ordered a second one for the other side of my e-bike

Light seems to work nice and bright but it's one button action so it's kind of a pain in the butt to pick up color and eats up the batteries but for what it is it's not bad you'd be better off using rechargeable batteries though and shipping wasn't the best cuz they were late so I couldn't have it on my son's bike in time for his birthday so that sucked

Got this to add extra light to my rides at night. It’s not the brightest, but I think it’s enough to be noticed! I’ve seen reviews that say to use zip ties and I would agree (though I didn’t need to) because the straps are not super long and every bike is different.

Let’s get right into would I buy these again and the answer is absolutely 100% these things are awesome I bought one for my motorized bike to highlight the engine and make me more visible so it’s both an aesthetic and safety feature and I can tell you on both aspects of it I love it and if you were to use these to light up the ground under you it lights up very well I’m not saying it’s the brightest if you’re expecting like neons on a car just forget about it but if you’re expecting a normal person‘s perspective of a I think five LED light shining down and lighting up the ground or in my case the engine this thing is awesome and with multiple modes depending on what I’m doing or how I’m showing it off if it’s for visual affect whatever or even safety feature this thing is top-notch the battery life is great as long as you have durable batteries that means spend the extra two dollars don’t be cheap and grab the two dollar pack of batteries by the five dollar pack of four batteries it’s not gonna kill you and it’ll get you more than your moneys worth and if you’re like me you say screw that and you buy rechargeable batteries for this rechargeable AAA batteries of a good alkaline brand you spend maybe 20 bucks for four batteries and a charger and you charge them once every two weeks or so and that’s a good deal a good price and a great feature to any bike whether you have an engine or not in my case I want to highlight my engine I spend a lot of time building these things and getting them just right where they can make ours an hours one-way trip without an issue and look good in the process for me it’s a great buy and as a safety aspect when you’re a bicycle what do you have an engine or not running on the road you need to be seen but especially if you have an engine and I say that because when you see a bicycle as you’re driving you’re expecting around 7 miles an hour 10 max however a motorized bicycle can go anywhere between 20 and 70 miles an hour they’re not expecting you to be going that fast which means if you go to make a turn they may think they have time to pass you they may think that they have time to get around you or anything like that you need to be as visually a parent as you can because you are a little bicycle compared to a 2000+ pound vehicle these things will help you shine bright!! UPDATE JUNK!!Absolutely JUNK!! Stopped working second ride!!

Simple to install. I thought it would come with a USB charger, but no, it takes batteries. As far as functionality, it's really not. The light in the marketing photo is misleading. If it would have been that bright or brighter, I'd be happy and this would be functional. This light is like a night light. I'm not wasting any more money on batteries when the batteries I have in there die. Find something else, people.
