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

I bought this light last year when preparing to ride on early summer evenings. This light is very bright and observable at night. It's light weight and was easy to install as you can either clamp it to the seat post, or as I use it, clipped onto the utility bag I have strapped onto the rear underside of the seat that has a nice band to slide the clip on.

I rode the bike for at least an hour after dark 3 or 4 times a week, and the batteries are still good.

This is a good purchase.

Great bright lite for a bike. Easy to install and yet very bright. Has the option of blinking or steady light.

These lights are worth the price you pay. Fitting into a bike seat is extremely easy and the light is visible uptil more than a block in the night. Havent yet used in the rain, however cold weather doesnot affect the system. Would definitely recommend it to anyone looking for a safe bike ride in the dark.

For the money, works well, and as others have stated, batteries last long due to the use of LEDS. Small, so you can take it anywhere, and clip to your clothing or back pack when walking, biking or hiking, etc. Wish I could find an inexpensive bike light for the handlebars, so I generally use my Petzl.

Good rear bike lamp
Bright enough to be visible to cars.
Option of having it flash, although I read sometimes drunk drivers head towards flashing lights - don't know if true.
Easy to attach
