Absolute Best Super Bright LED USB Rechargeable Bike Light & Horn Combo with Mount for All Bicycles. Very Loud Sounding Horn with Flashing & Steady Light Capability. Waterproof.

The light is very bright and the sound of the horn is very high. The missing start was caused by the way it is fastened: I don't expect that rubber to last very long. Also, if you want to charge it out of the bike, you have to bring the horn together, what causes it to unfasten/fasten everytime you want to charge it -- somehow bothering.

The light is extremely bright--much better than the one I already had. The horn is most effective on residential streets. On major arterials, it tends to be overwhelmed ambient traffic noise. Still, it is much better than a bell in any level of traffic.

mine was an already opened package so there were no instructions. what is the bottom round area with 2 meeting arrows ? i did find the charge post. oh well

The loudness of the horn is disappointing as is the battery life of the lights.

wow super brite easy to install a winner

Used for 2 weeks and it completely stopped working. Definitely not waterproof... Very disappointed.

Awesome

Very easy to install. It literally took me less than 5 minutes to put this on my bicycle. It looks stylish and adds safety to my rides now. I Like that it has three light settings sand very bright. I can use high beam, low beam or flashing. Very easy to use & the horn is Very Loud!! Scared me the first time I used it because it was so loud! Great product and definitely a great saftey item for a bike rider as myself! Good product for the price!
