5-LED Bicycle Front Headlight & Rear Tail Light, Black, 2 Light Set
You need it for Bike to the Beach and you'll need it in the fall when the sun sets early.
The White battery operated head light is bright... with an option that you can be seen at night from the side as the light emits a beam to the front and a circle of light from the side that can be seen by an approaching vehicle.
The tail-light is not only a battery operated light that flashes in quite a few options but is also a reflector. I've seen red tail-lights that are either a reflector or a battery operated light, but not often seen as both at this price point.
