StreetGuard Cycle Beacon

£28.95

110dB Horn & COB Headlight in One

The cyclist's nightmare isn't the road. It's the driver who never looked.

You've felt it. The car edging into the bike lane. The pedestrian stepping off the kerb with headphones in. The lorry whose mirror you're invisible in. You ring your bell — that polite little ting — and nobody hears a thing.

Most bike bells were designed for a country lane in 1952. British roads in 2026 are a different animal.

The StreetGuard Cycle Beacon was built for the way people actually cycle now — through traffic, in the rain, in the dark, alongside drivers who are texting at the lights. It puts two things on your handlebars that have never belonged together until now: a 110-decibel electronic horn loud enough to cut through a closed car window, and a 12-bead COB headlight bright enough that no driver can claim they didn't see you.

One unit. One mount. One small black housing about the size of a matchbox — 7 cm × 4 cm × 4 cm (2.76" × 1.57" × 1.57").

Why 110 decibels changes the maths

A traditional bicycle bell sits at around 75–80 decibels — roughly the volume of a normal
conversation. From inside a car with the windows up and the radio on, that bell does not exist.

110 decibels is in the territory of a car horn. It is the volume a driver's brain is already trained to react to. That is the difference between being heard and being hit.

And because the horn fires from a wired remote control that mounts within thumb's reach on your grip, you never take a hand off the bars to warn someone. You see the danger, you press the button, the driver looks up. That is the whole sequence — under a second, both hands still steering.

Built for British weather, not catalogue photos

The housing is ABS and rubber composite, sealed and rated IPX5 waterproof — which means it shrugs off the kind of horizontal rain that ruins most cheap electronics on a Tuesday morning commute. Dustproof. Shockproof against the pothole you didn't see. It's the part of your kit that you stop thinking about, because it just works.

A headlight that earns its place

Four modes, calibrated for real use:

● Highlight — up to 225 minutes of full-beam output for unlit country lanes

● Low light — up to 350 minutes for lit urban roads where you mainly need to be seen

● Flash — up to 420 minutes of high-visibility pulse for dawn and dusk commuting

● SOS — up to 610 minutes, for the night you're stranded and need to be found

The 1200 mAh lithium battery charges via standard USB. No proprietary cable, no fiddly mount, no tools — fixed to almost any handlebar with the supplied strap in under a minute.
