The Radial Pharos Rear Safety Light offers a small easy way to be seen from behind. If you need something to put on your bike quickly or in addition to your current light, this is a fairly priced option.

It's a compact light with an anodised machined aluminium body, making it robust and good looking.

The Pharos is easy to fit to your bike with a flexible rubber strap. It takes seconds to fit and remove the light, perfect for those who lock their bike up in public.

It's operated by pressing the light itself. Pressing it once puts it into flashing mode, a second press gives a continuous beam and a third press turns it off. It's incredibly simple to work.

The three-watt bulb is powered by two CR2032 batteries. From this you get a burn time of 30 hours on continuous and 90 hours in flashing mode. Both are quite healthy numbers in terms of battery life. The light will start to fade as the batteries run out though, so watch out for this.

It is water resistant and I found it held up well in light showers and no water managed to get inside it.

It isn't a light that you would chose as your sole illumination, but in addition to your current set up or as an emergency back up light. It's quite bright though, and in flashing mode you will be noticed which is the main aim of the light.

At the price there are similarly-sized lights on the market and run times do vary. The Pharos has a good battery life in flashing mode which does give it somewhat of an edge.

Overall, it's a nifty little light that's easy to carry about with you as a spare. It looks good and fitting it to your bike is a total doddle.

The LED is probably consuming about 25mW, not 3W (The capacity of a CR2032 is around 200 mAh).

The description on the website https://www.radialcycles.co.uk/pharos-mini-rear-light-rli107.html does mention the front light having a 3W LED but the rating of the rear LED is not mentioned.

Also the text above states 30 hours but the website and the text further down says 60 hours on continuous mode. Which is it?

Steph - will the band on this fit ok around a 'normal' sized seat stay (~20mm diameter)? Cheers
