Radial Cycles Pharos front safety light



Great little addition to your current bike lights, or as an emergency spare

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Radial Pharos front safety light is small, compact and light. It's really easy to attach to your bike and can be fitted in seconds. A good little light as a spare or for added visibility.

Weighing in at 31g this little light can literally travel anywhere. It will fit in your pocket, bike bag or jersey if you don't want it on your bike all the time. It attaches with a flexible rubber grip that will fit most bikes with ease. The beauty of this is that you can quickly remove it when you lock up your bike and take it with you.

It packs a lot into a small light. With a white three-watt LED, it gives off just enough visibility in the city. This won't light your path on unlit roads but is certainly enough to alert other road users to you.

The light has two modes, constant and flashing. It uses two round, flat CR2032 batteries (included) and these last 30 hours in constant mode and 90 in flashing. Which is a fairly decent amount of time. The downside here is that it isn't rechargeable, but batteries are fairly cheap.

Operation is simple. You just press the actual light once and it goes straight into flashing mode, press again and it's in constant mode. One more press and that's it turned off.

The body of the light is anodised CNC machined aluminium and looks really good. It's also water resistant and will cope with light showers well without water getting into the casing.

The price is £8.99 and is cheap as chips really. It's a perfect spare light or additional light for more visibility. It stands up against similarly priced models on the market well. The Lezyne Femto Drive LED light has similar constant time for battery life, but the Radial outstrips it in flashing mode with an extra 30 hours.
