Question: Does it come with an attachment for a bike helmet?
Document: It is a super bright light, but it does not come with a way to attach it to your bike. You will have to take it to a bike shop to rig it or use quality zip ties.
I don;t think you can fix this. So keep your receipt and if you see something fishy starting to happen be careful, I had to come back to my car in complete darkness on the trail on my mountain bike, take a backup light. I didn't keep the receipt since it was so inexpensive I didn't care. I bought another one similar and this one works OK, no other friends who have similar lights had problems, so it's only a few of them I guess, just my luck!
If the link doesn't work, the title was initially: "Wide Angle Lens for MagicShine, Gemini, and many other Bike Lights / Headlight". Good luck :-)Having owned this for several weeks now, I can safely say this has truly made an impact on how safely I am able to ride and walk in low-to-no light scenarios. I was used to cars swerving away from me in almost-too-late scenarios before I got this lamp and now they start giving me breadth VERY far away!When I come to intersections, cars that ordinarily would have been ignoring me (or not noticing altogether) are now stopping and waiting for me to cross rather than jet out and expect me to be sure to miss them.
I love riding my bike at night so I needed a good bike like this and it works like a headlight on a car!!! !While riding with this light I get more respect from vehicles, they also dim their headlights when I come near them.If I have 5 bicycles so I switch them often, sometimes I get tired changing the light to other bikes so I plan to buy more lights so it will be more easier on me. However I would recommend this light to anyone who wants to ride safe and be seen while riding at night, plus this light is not only just good for a bike, you can use it as a flashlight to see when there is no light around whether you fixing or looking for something.
I recently purchased this headlight for my bike and so far the battery has worked great and lasted at least for 4 hours straight. I've had no problem recharching it.The problem is that tha mounting is not that great. While trying to adjust it a tiny piece of plastic that holds the actual lamp on its socket broke and now I have to tie the lamp with the wire so it won't come out while riding it. I cannot glue it because then it would be a big problem to unmount the whole thing when you need to leave your bike unattended and chained.The lamp has  an extra piece  that allows it to move up and down and it's only held by a thin screw, so every time you go on a bumpy road it starts pointing downwards and you have to manually adjust it everytime no matter how hard you  tighten it.
I plan on buying another one to put on my wife's bike.Oh yeah it also comes with a head light strap. I have thought about buying another one for when I take my mountain bike on some night rides so I can mount it to my helmet for even more light. For the price and performance, you can not beat this light!
It's a very bright light, but it's made by a sketchy Chinese knock-off company--it comes with NO instructions, just a weird "warranty card" written in nonsensical gibberish-English (and I am a language teacher and a polyglot, who is used to figuring things out, and I am not a bigot! This is just REALLY bad). There is no way mount the light to either my bike or my helmet. I'm sending it back. I wish I'd read all the reviews before buying!
Simple!The battery is small and lightweight. It straps right under my handlebar stem nice and snug with the velcro straps so everything is right there on the handlebars. Note: There is enough wire from the light to the battery to easily mount the battery farther back on the bike (or on your helmet with the battery in a back-pack or hydration pack. )While it's charging, the wall adapter will show either red (charging) or green (full charge) - Convenient!Performance-wise, This Thing Rocks!
This is a must if you do not want a narrow beam.The only thing that would be a negative is that the button stays lit when you turn the light off, I think this would drain the battery after a while. Not really a bad thing just a nuisance since when I am not using it I have to unplug from the battery. I did not use the helmet accessory nor do I plan to. I do not really need it.Otherwise, If you are looking for a great, reasonably priced bike light save yourself the time looking and buy this one.
I am not a fan of having to push it a number of times to get it to the off position when I am done using the light. If I had my way, it would have like high and low and off. I have no use for strobe. Its bright as all get out and it makes me nauseous.I don't know yet where to get accessories for this light. I will definitely be looking for one which mounts to a helmet. I'm not a fan of the idea putting the included cotton elastic band on a plastic shell bike helmet, as it will probably just slip up and off.
Answer: yes
