This stylish 1 watt LED mounts to the front of nearly any bike. It also features an auto-sense feature, enabling it to automatically turn on and off, depending on lighting. The Torpedo runs on two AA batteries and is a great way to add a touch of class to any bike. The light housing is made of chrome colored plastic. While nearly identical to the Linus front headlight, we like the Soma's auto-sense feature. It's a nice touch that works well.
