YSD DL09 LED Dynamo Bicycle Light, Dynamo Bike Headlight&Motorized Friction Generator. 100 Lumens, Waterproof, Easy to Install, Never Need Battery for Bike Light

It works great, the electric components seems well protected. The light is not impressive, but enough to be seen by cars and useful by night. Looks are fine but can be improvedI love it because my daughter doesn't need to turn it on, she just have to start pedaling and the light turns on

I was initially excited to receive this product. When it arrived, it seemed well made but I ran into problems mounting it, that's why I only gave it a four star rating. The clamp that fits around the tube of my bicycle to connect the light is designed to accommodate a bike with a small, round tube. My Specialized brand bike has a slightly larger, rectangular shaped tube and the clamp will not go around it.I'm considering ways that I can modify the design, maybe by placing the light on the back of the bike (where the tube is smaller) instead of the front or finding a different clamp. I may end up returning the light. I think this could be a wonderful product but the manufacturer will need to include several clamps to accommodate a variety of brands.

Instructions are a joke. “Step 1: install product”.

GREAT ITEM.. The slightest turn of the generator turns the light on at full strength. Its easy to install and very bright.

I only had one ride last night after installation yesterday. I am pleased. Enough light emitted to see obstacles and for cars to see me coming. Can't speak to durability yet- one ride. I hope it stays where I put it. It should as it has a nice gasket to prevent slippage on front fork.

Good

Works great. Only thing I did different was to get better screws to secure it to the fork. Edit: I would add a 5th star if it had a capacitor to deep it shining at stops

Good product. Easy to install.
