Bike Tail Light

Easy to use. I use the clip to attach to the back of my seat bag, and the strap to attach to my helmet. Very bright, visible in sunlight.

I happened to see one operating after dark and the pulsating red light was wonderful. It has three levels of Brightness. On fully, flashing fast and flashing slow with a fully bright red light. Good for cycling at night or out as a pedestrian after dark on rural frequently traveled roads used by vehicles. There is a clip to attach to the rear of a bike. If you ever need to change out the button battery, a small screw driver is included in the small box used for holding the flasher. This is a nice novel lighting system on the go.

They work well. The batteries last a long time (I make 30 minutes commutes weekly and it lasts a over a month. One pack comes with a screwdriver to help replace batteries

Very nice little blinking lights for safety during hours of reduced visibility. They have a spring clip and are easy to attach to a belt, safety vest or backpack.

Work great!

Works great clipped to shirt for safety while walking at night. Very bright, three modes. Gave it 3* because it is not rechargeable; and agree with other reviewers that the battery would be difficult to replace, despite including a mini-screwdriver. (But have not used it long enough to know how long the battery will last.) Just no room to work with given the clip is not removable. Despite other reviews, the clip, while plastic, does not seem particularly fragile.

You get what you pay for. Cheap. The battery life is short and it is impossible to remove screws to replace. The supply a micro screw driver but good luck loosening any of them.

Ordered a pair. Immediately out of the box, one lost its hinge pin. Turns out it didn't matter, because the lights were not functioning on it (and yes - I tried swapping the batteries). The second one is functional - but be forewarned, these lights while functional, are very low quality. Second one tried to lose the hinge pin as well. Four VERY SMALL screws have to be removed to swap batteries. Not worth my time to process an exchange or return. You get what you pay for.
