Review on 🚴 Ultimate Safety and Convenience: USB Rechargeable Bike Front Light with Solar Power, Bell Horn, and 350 Lumens LED" by David Boone

On the plus side, very bright light (350 lumens) and very loud beep. It is also able to work for up to 2 weeks without charging the batteries. The top of my device got wet from rain. The horn button appears to be fairly waterproof, but the main unit's top case is a different matter entirely. After drying for 14 hours, there is still condensation in the transparent plastic cover of the solar panel. Also, the horn electronics are shorted - the horn randomly turns off when plugged in, or just makes an anemic chirp. There is also a water leak from the horn connector which entered through the solar panel cover. Leaving the device in the sun all day won't charge the batteries, so I think the solar function is more of a gimmick than anything useful. Estimated 1 to 1.5 hours per week with high beam (with very frequent honking while driving), the device must be charged once every 2 weeks. The red light flashes when the batteries are low. Charging takes about 6-8 hours. Another problem: It's really annoying to cycle through 4 lighting modes just to turn off the device. Depending on your driving style, the horn catch may come loose when you press it. The horn clasp is a rubber band, not a stud. Since most horn and bugle combinations are like this, I wouldn't deduct points for it. Just something to be aware of. Overall, this is a good light, but it's not protected from rain or water. And the solar panel feature might be a publicity stunt. If you decide to buy, don't let it get wet!
