Front bike lights for road, gravel and night rides
A front bike light should make you visible and, away from lit areas, show you the way. In the UK, the Highway Code requires a white front light at night. Then choose the power according to the terrain: a modest lamp is enough in town, while a headlight of more than 1,000 lumens becomes useful on an unlit gravel track.
Being seen or seeing the road: which front light?
A front position light signals your presence to other road users: in the UK, a white front light lit at night is the minimum required, and rules vary from one country to another. A headlight goes further and lights up the road or the track in front of the wheel. On the road, you need to be seen before you need to see; on a forest track or a white gravel road at night, what counts is being able to read the terrain. A second front light lets you combine a wide beam with a long-throw beam.
Lumens, lux and beam
Lumens measure the total amount of light emitted by the lamp, lux the illumination received at a given distance: a 30-lux dynamo headlight concentrates its light on the road, whereas a 1,000-lumen USB lamp may scatter some of it. The shape of the beam counts as much as the power. A beam with a sharp cut-off lights up the road without shining into the eyes of oncoming drivers; a powerful round beam, popular on trails, should be lowered or dimmed as soon as you meet someone.
Rechargeable, dynamo or e-bike battery
The USB rechargeable lamp dominates on road and gravel bikes: it attaches in a few seconds and offers several modes, whose run time varies widely. A dynamo headlight, powered by the front hub, lights the way without recharging, an asset for long-distance touring. On an e-bike, a headlight connected to the battery comes on with the system, provided its voltage range is respected.
Mounting and gravel use
Most lamps attach to the handlebar with a strap or a clamp; check your handlebar diameter and the space left between the bike computer, the handlebar bag and your hands. A mount under the bike computer frees up the handlebar. On tracks, a helmet light complements the one on the handlebar: it lights up wherever you turn your head, in corners.
Rear lights and gravel electronics
A headlight goes hand in hand with a red rear light: rear bike lights cover the rules and mounting options. Bike computers and lamps often share the same mount: see bike computers and GPS and the whole of gravel electronics.

Frequently asked questions
How many lumens for a front bike light?
It all depends on the terrain: the lamps on this page range from around 150 lumens, enough to be seen in town, to more than 4,000 for night-time trails. On an unlit road, the shape of the beam counts as much as the stated figure.
Can a powerful headlight dazzle on the road?
Yes. In the UK, the Highway Code states that you must not use lights in a way that would dazzle or cause discomfort to other road users: aim the beam at the ground, a few metres in front of the wheel, and switch to a lower mode when you meet someone.
Is a helmet light enough?
No. In the UK, the Highway Code requires the bike itself to have a white front light lit at night. A helmet light is a very useful addition for gravel riding or mountain biking, to see into corners and read the terrain.
How much battery life for a night ride?
It varies widely from one mode to another, and each product page gives the run time for each mode. Work it out on the mode you will actually use and keep a margin for the ride home.
How do you fit lights to an e-bike?
Many e-bikes let you connect a headlight to the battery. Choose a model compatible with the system voltage, stated by the manufacturer, or go for a standalone rechargeable lamp.
