About Rear Lights
Almost all bicycle rear lights use LEDs instead of filament bulbs as they are more reliable and use much less battery power, whilst also offering much higher levels of brightness. Used in flashing mode, they are very good at attracting attention from other road users. It's advisable to use at least two rear bike lights, a common configuration is one flashing and one in constant, this is highly advisable just in case one stops or becomes obscured.
In order to cycle on the road it may be a legal requirement in your country to use a light certified to a specific standard or an international equivalent. Most but not all lights sold on Wiggle are certified and labelled with a European CEN standard. Please check your country’s requirements to see if this is sufficient and if necessary contact the manufacturer to see if this light has been additionally certified for your country. Strangely some of the very best lights are not legal on their own and should be used with an additional legal backup light.

Magazine reviews for Knog Bullfrog 5 LED Rear Light
Review from Cycling Plus
This is a light unit contained within a silicone housing that also doubles up as the clamp. Sporting five LEDs powered by 3 AAA batteries, there are an assortment of flashing modes to choose from, as well as constant light. The run times were nowhere near the claimed times though, with a little over 132 hours in flashing mode, well under the claimed 220. Although not that bright in the light readings, the impressive thing about the bullfrog is its visibility. The whole silicone body more or less lights up in teh dark, making it highly visible from all angles. The lack of mounting makes it simple to fit almost anywhere, wlthough on smaller diameter seatposts, it did tend to move over the bumps over the bumps when wet.
In conclusion...
Soon ends up beige with dirt, but a good performer nonetheless.
