Comments about Knog Blinder 4 USB Front Light:

It is a great light for you to be seen in the night or even the day, its USB charging system is very versatile and the attachment system is cool too, but it seems a bit weak.

Comments about Knog Blinder 4 USB Front Light:

This light is pretty awesome. Probably one of the brightest lights Knog produces and lighter than many of their other offerings. It's bright enough for daytime use, but I use it for my commutes and night group rides. The USB charging works nicely but the battery only lasts about 3 hours total, requiring frequent recharges, which is no big deal since the batteries are rechargeable. The mounting system feels good and allows for quick removal and installation. On my particular light, it rattles a little when going over bumps if it is at a certain angle. A little annoying but it's probably not a problem experienced by all of these lights. The light does not move around on the handlebar and feels solid. It won't pop off inadvertently.

The housing is anodized aluminum and is not the normal Knog rubbery material. This reduces weight, which is nice. I'm also pretty sure the light is completely waterproof, so it would work well as a rainy day light.

    This tiny little light just blazes a path through the night. For commuting and light trail riding this is the bomb.
