I know this is a not so good topic for asking about vont illumination headlight for the bike, but I need powerful headlights in front of the bicycle. I travel a lot by bike and I need to freshen up a bit. I found on the amazon https://www.amazon.com/Vont-Rechargeable-Illumination-Resistant-Accessories/dp/B078TB9TMK vont bike headlight and i don't know if they are good or not. Maybe someone else has bought and knows how they are in quality. I need them to be charged with sunlight, because I walk during the day, and sometimes at night . But they have to be strong to beat the loud light within a kilometer radius, to make sure that I have no obstacles, that there was once a situation where I could lose my life because of the weak light that I had .
