  • Great light!
I actually bought 2- lights and I placed one on the front and one on the back of my 5- year old granddaughters bike helmet. In flashing mode she could be easily seen from quite a long distance. Several of my neighbor's saw her on her scooter with the lights flashing and they wanted to know where they could purchase some for their own children. So many people text, talk or just don’t pay any attention so our kids need as much visibility as possible in order to safely be able to enjoy themselves outside. My granddaughter just thinks they look good so it’s easier to get her to willingly put on her helmet while riding. Great product I installed both on the same helmet in less than 5- minutes. ... show more

  • Not magnetic / poor quality
Not to be dramatic but this truly sucks lol. First off the light is not magnetic, I attached it to my helmet anyways with an adhesive, it worked for ONE 30 min bike ride before dying - go to plug it in, and it won’t recharge, rendering it useless. No go personally

  • Not Magnetic
Contacting company. It won’t adhere to my Thousands 2.0 helmet. It would automatically come on like it should but not stick to helmet. Like there’s no magnet.

  • Not magnetic
Light is not a magnet dispite the photos and videos that make it appear as if it is. Seller refunded my purchase and said the light is only compatible with their helmet.

  • Great product and service!
The media could not be loaded. First I ordered a helmet that included the light but it wouldn’t work, therefore I nade contact with Mountalk through their official website and they were really kind and helped me get a new light. This one works perfectly and I feel really happy with their services. I completely recommend it. ... show more

  • Just like the official Thousand lights!
These will work on your Thousand Chapter helmet! I bought a few extra so I have them on-hand and keep them in my pannier.
