Planet Bike Blinky "3" 3-Led Rear Bicycle Light

Bought two of these for daughters electric razor scooters. Very bright and easy to see, these flash or stay on constant. They definitely improve the visibility of the kids at night.

Great light. Survived a snowy winter and lots of rain storms over the past two years. Still working well.

The light is great! It's bright, reliable, and easy to understand. Also great to take off when you don't want to abandon your light.

Simply cannot be beaten for [...] bucks.

I keep mine on the seatpost, where it can be easily turned on and off without dismounting. Cargo on my rear rack blocks it from view, however, so in that event I just unclip it from the mount and strap it to my rear reflector with some bands of rubber cut out of an old innertube.

I ordered two for my and my wife's bikes. No instructions were included but it only took a minute to figure out that you need to remove the red cover to put in the 2 INCLUDED AAA batteries. I really like that these run on AAA instead of lithium batteries due to ease and cost of replacement.

Mounting was very simple for our Raleigh & Trek bikes - right on the seat post. My only concern is that after tightening the screws the whole unit is a little wobbly. This shouldn't be an issue since they are situated under and protected by the seats.

I tested the 'steady' and 'blink' functions which worked fine. The lights are amazingly bright so don't look directly at them when you put the batteries in. Visibility is excellent and you could definitely use this during the day. At night you may be mistaken for some sort of emergency vehicle. At any rate - great for safety. I highly recommend.
