Bicycle Light Bar — Wide-Beam LED Bar with Integrated 130dB Horn

Why an Ebike Light Bar Beats a Single Round Headlight

The shape of the beam matters more than most riders expect. A conventional round torch-style light throws a tight circle, which is fine for reading the tarmac ten metres ahead but leaves the edges of the road, the kerb line and the mouth of the next junction in the dark. A light bar spreads its output horizontally instead — the same reason vehicles use wide light bars rather than a single spot. On an unlit lane or a Welsh back road at 15mph, seeing the verge and the potholes at the edge is what actually keeps you upright.

Being seen is the other half. A wide bar of light is read by a driver as something substantial and closer than they would judge a single small point of light to be. Drivers routinely misjudge the speed of an approaching e-bike because they are estimating from the light of a pedal bike, and a wider, brighter front signature narrows that error at exactly the moment it matters — when someone is deciding whether to pull out of a side road in front of you.

The Horn Is Not a Novelty

A bicycle bell is a polite request. It works on a shared path, at walking pace, when the person ahead is expecting it. It is close to useless against traffic noise from inside a car with the windows up and the radio on, which is precisely the situation where you most need someone to notice you. A horn rated up to 130dB carries through that. Used sparingly — when a car is drifting into your lane, or edging out of a junction without having seen you — it does the job a bell cannot.

Use judgement with it. At that level it is genuinely loud and it will startle pedestrians, so it belongs in traffic, not on a towpath. The separate switch is what makes that practical, because the horn is only ever sounded deliberately.

Your Legal Obligations and What Else You Need

Riding on UK public roads after dark, you must have a white light at the front and a red light at the rear, plus a red rear reflector and amber pedal reflectors. This unit covers the front. It does not cover the rear, so you still need a red rear light and your reflectors fitted — do not treat a bright front light as compliance on its own.

If you want a second, smaller front light as a backup or for daytime running, the Bike Light is a compact 57 g USB-C rechargeable headlight with six modes, and it works well alongside this bar — one steady for seeing, one flashing for being seen. Note that the two are quite different products: the compact light is a self-contained rechargeable unit, whereas this is a wired bar-and-horn assembly with a handlebar switch. If you want to confirm exactly how it powers on your particular setup before ordering, message us with your bike and we will check it for you.

Also worth considering if you are getting the bike ready for winter riding: the Mountain Bike Set Mudguards for the wet, and a shackle lock for the dark evenings when you are parking somewhere you would rather not leave the bike unattended.
